Requirements ~~~~~~~~~~~~ This program supports and requires Kickstart 2.04 (v37) or higher. It works on the internal serial port only. What is it? ~~~~~~~~~~~ My system often calls out automatically via modem. The UUCP software I use sometimes hangs on a call. It then sends error messages until I manually abort the transfer. This is very annoying since the call costs money. ToggleDTR is the solution to those problems. I use it to turn of the DTR signal for a few seconds when UUCico is spending too much time on a call - causing the modem to hang up. WARNING ~~~~~~~ This program is a *dirty* hack. It does access the hardware directly. These are the things you should know before running it: · Blindly accesses bit 7 in ciapra of CIA-B to control DTR signal. · Checks left and right mousebutton for abort using the hardware registers. · Does the inner loop while Forbid()ing multitasking to prevent hazardous trouble on the serial port. ============================= Archive contents ============================= Original Packed Ratio Date Time Name -------- ------- ----- --------- -------- ------------- 134 63 52.9% 13-Oct-93 22:40:28 ToggleDTR/Make 1372 914 33.3% 17-Oct-93 15:29:22 ToggleDTR/ToggleDTR 2526 1272 49.6% 17-Oct-93 15:28:06 ToggleDTR/ToggleDTR.doc 1376 924 32.8% 17-Oct-93 15:29:20 ToggleDTR/ToggleDTR.o 7398 2173 70.6% 17-Oct-93 15:29:12 ToggleDTR/ToggleDTR.s -------- ------- ----- --------- -------- 12806 5346 58.2% 18-Oct-93 12:56:30 5 files
