All rights reserved. 3Com Corporation Software Release SW/20-A/BSC/SDLC-NCS/1 Version 22010 March 1, 1989 Part Number: 86-0196-00 Revision 01 TO: CS/1 Users FROM: 3Com Corporation SUBJECT: SW/20-A/BSC/SDLC-NCS/1 Version 22010 DATE: March 1, 1989 Enclosed is a distribution tape cartridge containing SW/20-A/BSC/SDLC- NCS/1 Version 22010 (part number: 83-0166-03). This software, which is an updated version of SW/20-A/BSC/SDLC Version 22000, is to be used by an MCPU20-based CS/1 that is booted from an NCS/1. This release memo describes the bugs fixed since Version 22000, and the software's limi tations and known problems. Compatibility SW/20-A/BSC/SDLC-NCS/1 Version 22010 can operate with the following products and software releases: CS/1 running SW/20-A/BSC/SDLC Version 22000 or later CS/1-SNA running SW/1-SNA Version 13010 or later GS/1-X.25 running SW/1-X.25 Version 14030 or later CS/200 running SW/200-A/BSC/SDLC Version 22000 or later CS/210 running SW/200-A/BSC/SDLC Version 22000 or later IVECS running SW/IVECS-A Version 20060 or later NCS/150 running SW/150-NCS Version 10010 or later NCS/AT running SW/AT-NCS Version 11000 or later IB/1, IB/2, and IB/3 running SW/20-IB Version 11000 or later Personal computer running SW/PCS-XNS Version 10000 or later Table 1 illustrates the hardware and firmware compatibility for SW/20- A/BSC/SDLC-NCS/1 Version 22010. Table 1 Hardware/Firmware Compatibility Product Boards PROMS CS/1 SIO-16 No PROMS CS/1 MCPU20 M3 MMON 00D or later CS/1 EC/2 M1 IECM 01F or later If an Ethernet controller is used with the MCPU20-based CS/1, it must be an EC/2 board with 512 kilobytes of RAM. Also, the MCPU20 board must operate with a 96-TPI disk drive. Installing the Software For instructions on installing SW/20-A/BSC/SDLC-NCS/1 Version 22010 on the NCS/1, refer to "Installing Software" in the NCS/1 Installation and Operation Guide. Bugs Fixed The following is a list of problems that existed in SW/1-A/BSC/SDLC - NCS/1 Version 22000 or earlier and have been fixed in SW/1-A/BSC/SDLC- NCS/1 Version 22010: Setting the EOM parameter to disabled no longer causes problems when you trans fer data to an X.25 host. Previously, if you set this parameter to disabled, it caused the End of Message bit to be turned on on every SPP packet. This caused data forwarding problems. Setting the ECMchar parameter to disabled on CS/1s using the SIO-16 board no longer causes null characters to be transmitted in separate packets. Previously if you set the ECMchar parameter to disabled, each null character was sent to the CS/1 in a separate packet, increasing network traffic and data corruption. Known Problems The following is a list of Version 22010's known problems: Due to a memory limitation, the SHow CONFigurationS and SHow MACros commands no longer display output in alphabetical order. On the SIO-16 ports, the help menu of the BAud parameter displays LowAutoBaud and HiAutoBaud as options of this parameter. The SIO-16 boards, however, support only single-range autobaud. Setting the BAud parameter to LowAutoBaud or HiAutoBaud does not affect the baud rate, which ranges from 50 to 38.4K. Limitations The following is a list of Version 22010's limitations: The display generated by the SHow AllSessions command is limited to a maximum of 50 lines. Only three echo requests may be outstanding at any given time. If more than three users simultaneously enter the PIng command, the following message appears: Can't Ping now - try later Macros are cached in local memory on the CS/1. If you change or delete a macro, there is no guarantee that the change will flush the macro cache. This can cause un expected results when macros are executed. To ensure proper execution of macros, use the ZeroMacro command to explicitly flush the local cache after changing or deleting a macro. If the CS/1s on the network receive file service, including macro file service, from an NCS, you should flush the macro cache in each Communications Server bound to the NCS every time a macro is changed or deleted on the NCS. If an NCS/150 or NCS/1 is providing the file service, use the REMOTE command to access each CS/1 bound to the NCS, and then use the ZeroMacro command on each CS/1 to flush the macro cache. If an NCS/AT is providing the file service, use the utility on the NCS/AT. For example, at the utility prompt of the NCS/AT, enter the following command: oneachserver -B zm The Sysgen program is not available on the NCS/1 for SW/20A/BSC/SDLC Ver sion 22010. The MacType parameter should not be set to IEEE.
