However, saved startup configurations will not work when using the 3+ Startup diskette on a Macintosh netstation connected to different AppleTalk network (because this confuses the 3+ Prep file). User 2-4 If your Macintosh netstation beeps during startup it indicates that 3+ for Macintosh has failed installation. The 3+ icon in the Welcome to Macintosh box will be displayed with an X through it, indicating an unsuccessful startup. User 2-4 When booting your Macintosh netstation with 3+ for Macintosh, be sure not to hold down the 3 key (character key on the keyboard, not the keypad 3). Holding down this key prevents the 3+ for Macintosh system files from loading properly, and you will not be able to login. User 2-6 When using the 3+ network, the Chooser must indicate that AppleTalk is Active at all times. If you click Inactive, your netstation will not be able to access the server. If this occurs, open the Chooser from the Apple menu, click the AppleTalk Active button, and reboot your Macintosh. Rebooting your Macintosh is necessary to establish the link between your netstation and the server. By failing to reboot, the network name will not appear in the "Choose a network" list. User 2-6 If the Login box in the Chooser remains dim during any log in attempts, the RAM cache on the Control Panel may be set too high. For example, with a Macintosh Plus a RAM cache greater than 256K could cause this to occur. To lower the RAM cache; close the Chooser, select the Control Panel under the Apple menu, lower the RAM cache and close the Control Panel, open the Chooser again, and login to the network. User 2-7 If a large number of domains exist on your network, not all of them will be displayed in the Login box. To log in as a user in a domain that is not displayed, enter your user name and domain in the Name box using a colon to separate them. For example, Jeff Mason:HQ. User 2-18 The 3+ Prep file created to automatically login users and link folders and printers upon bootup only works on the AppleTalk network on which it was created. To create or change the startup configuration, open the Chooser, log into the network, link to the desired shared folders or printers, click Status in the 3+ Network Window, click Save as Startup, and click OK. To delete the startup configuration, open the System Folder and drag the 3+ Prep file into the trash can. To disable 3+ Prep when rebooting your Macintosh, simply hold the mouse button down after the Welcome to Macintosh is displayed. User 2-23 Users are reminded to choose Shutdown before turning off their Macintosh netstations. The recommended procedure is to save your latest work, quit your application, and choose Shutdown from the Special menu in the Finder. Shutdown unlinks all network objects, logs you out of the network, and ejects any diskettes in your netstation's drives. User 4-1 If for any reason, you decide to rebuild your desktop on the network (by holding down the Command and Option keys when starting up or returning to the Finder), only do so from the Home Folder level or another first level shared directory (such as 3Plus or APPS if shared by the server-user). User 4-1 Switch launching to 3+ shared folders is not supported in this release. Attempts to switch launch (while holding down the Command and Option keys and double clicking on the Finder icon in a system folder) to a shared folder will be ignored by 3+ for Macintosh. Putting a System or Finder on a shared folder will not cause switch launching to occur automatically (as it does on hard disk drives). The ability to switch launch will be included in a later release of this product. User 4-14 Macintosh netstation users linked to shared folders with Write/Create access rights can copy files to the shared folder, but not see them. IBM PC or compatible netstation users can use the DIR command to see the names of all files in a directory with Write/Create access rights, but cannot read them. Versions of MacTerminal prior to 2.0 are not supported in this release of the product. User App. Status message " A is not responding...Retrying . Press and . to cancel ". An example of a network server is Marketing:HQ:Fisher. This message appears when the server fails to respond to requests, and informs you that your Macintosh netstation is repeating a request to the server that has not been answered. By taking no action, the retry will continue indefinitely. Press and a . (period) to end the retry. This status message has no ID or Type designation because it reflects status rather than any error condition. When you cancel the retry, all connections to the server from your netstation are lost. You must reboot your Macintosh netstation and login again. .H1;File System Information User 4-7 A Macintosh user will be unable to create or move a folder into another folder if the full pathname of any folder or file exceeds a 94 character pathname limit. This still permits a fairly deep folder environment (approximately 9 levels deep with large folder names). If shorter names are used, still greater depth is possible (subsequent renaming may be prevented if the 94 character pathname limit is exceeded). If you share directories that are deep within an existing folder hierarchy, the maximum depth of any newly shared folder is restricted because of the pathname length limit (pathnames from the root directory). The 94 character pathname limit is further explained under the IBM PC Netstation Information section of the release notes. User 4-13 Shared folders, or folders that contain shared folders, should not be renamed or moved. Users linking to a shared folder that has been renamed or moved will be unable to access the files and may receive an error message. If you want to change the name of a shared folder, unshare the folder first, then reshare it with a new name. If you want to move a shared folder to another location, unshare it first, move the folder, then reshare it. A folder can be assigned more than one shared folder name. It is not advisable, however, for a user to link through two different shared folder names to the same folder. Doing so may lead to the accidental deletion of files. Both shared folder names actually represent the same information on the server's disk. When attempting to copy a file from one to the other, data will be lost. The Finder will present a message asking if the user wants to replace the existing file in the destination folder with the new one. Since these two files are actually one with the same name, the Finder is trying to replace that file with itself. When the user clicks Yes, the Finder will delete the file from the destination folder before it attempts to copy the file from the source folder. As a result the file is mistakenly deleted before it can be copied, and its data will be lost. .H1;Application Compatibility Information User 1-6 The developer's tool ResEdit (version 1.0) is limited to work only on files in the root level (the window that opens when you double-click on the shared folder icon on the desktop) of 3+shared folders. To use ResEdit on a file outside of the root level, first move the file to the root level. User 2-16 To use AppleShare and 3+ for Macintosh from the same diskette or hard disk, start with an AppleShare boot diskette (because AppleShare modifies the System file). Copy 3+ File, 3+Print, and 3+ Icon Giver from the System Folder of your 3+ShareUser for Macintosh diskette to the System Folder of your AppleShare diskette. User 3-2 To print using the Cricket Draw application, you must rename the 3+ Print file in your system folder to LaserWriter. Cricket Draw only sends files in a PostScript format when the 3+ Print file is named LaserWriter. Renaming 3+ Print will not affect any other 3+ for Macintosh network operations. The Chooser will still show the 3+ Print icon, but it will be named LaserWriter. User 3-6 For best results with PageMaker 2.0, use the Apple LaserWriter driver. Permanently downloading the Aldus Prep file causes the LaserWriter to run out of memory very quickly. To download Aldus Prep temporarily, open the PageMaker Print dialog box, hold down the [Option] key, and click Print. Click the Make Aldus Prep permanent checkbox to remove the X. Then send the document to be printed. For complete information on this PageMaker option, see "Using PostScript Options" in your PageMaker manual. Only PageMaker versions 2.0 and later are supported in 3+ for Macintosh. User 4-16 Occcasionally an application may generate a system error with-out breaking links to shared folders. The server will try to reestablish a link to the shared folder or folders for approximately two minutes. After that time, rebooting and logging into the network from the same netstation should allow you to link to the shared folder again. If an error message is displayed when trying to link to a shared folder after logging into the network from the same netstation, ask your Network Administrator to use the Unlink User function of the Admin application to unlink you from the server. User 4-18, Only Excel versions 1.04 and later (versions designed to use 4-19 with AppleShare) are supported. Switcher will not be supported in this release of the product. .H1;IBM PC Netstation Information IBM PC or compatible netstation users should exercise caution B in copying Macintosh files. If a file is created on a Macintosh netstation and an IBM PC or compatible netstation user attempts to copy it, the file's resource fork will (if present) not be copied and the Macintosh attributes will not be carried forward. Without this information the file will not be accessible. See Appendix B of the 3+ for Macintosh Supplement for complete information on the Macintosh data and resource forks (Appendix B covers the Macintosh service parameters; Macintosh threads, MS-DOS data fork extension, MS-DOS resource fork extension, and MS-DOS file extension mappings). User App. Because of the way pathnames to server directories and files are D managed in Share (DOS), there is a limitation on the depth of a folder hierarchy in terms of a maximum DOS pathname length. The current limit is set at 94 characters and includes the drive ID ("c:\x\y" is 6 characters long). Folders created on a Macintosh that have names that are not legal DOS names will always have DOS names 8 characters in length or less. User App. Renaming of folders will not be permitted if the length of any D folder or file pathname will result in a violation of this 94 character pathname limit. IBM PC and compatible netstations users should know that the file/folder name length of the DOS directory listing being displayed as 0 (zero) is valid for applications and some types of documents when doing a DIR listing. The DOS DIR directory command can display the file/folder name length as 0 (zero), but users should be cautioned against deleting this file without first using the MACDIR command. This is due to the differences between the DOS and the Macintosh File Systems. A zero length file may be an empty data fork for a Macintosh file. Use the command to verify the full file/folder name. MACDIR will display a directory somewhat similar to a DOS directory listing, but with Macintosh file system information added. The full name of the file/folder within the Macintosh file system can consist of up to 31 characters, some of which are illegal in DOS names, such as spaces. File naming, therefore, will not necessarily look the same. If you are unsure about the status of a file seen in a DOS DIR listing, use the MACDIR listing before deleting anything. Refer to the 3+ for Macintosh Installation Supplement, Table B-1, for an example. .H1;Multiple Server Support In this release, Macintosh netstations are not able to use 3+Route to access shared folders and printers on remote servers via modem and telephone line connections. 3+Route can continue to be used by IBM PC and compatible netstation users in this manner and will continue to support the sending and receiving of messages via 3+Mail. Full 3+Route support for Macintosh netstation users will be included in a future release. However, you can configure your network to support multiple servers by connecting the servers with Ethernet cabling. Each server on the network can have an Ethernet segment and an AppleTalk segment attached to it. Macintosh netstation users can then access shared folders or shared printers on any server on the network.
