I fetched it from SIMTEL, and it compiled OK, but when I run it I immediately get a segmentation fault, before it even prints the sing-on message (the printf is the FIRST executable statement!). I contacted Rick Conn and he said he wrote this for System V. We are running BSD 4.1c (soon to convert to 4.2). For comparison, umodem has conditional-compile flags for JHU (Johns Hopkins), VER7 (Version 7, also good for Berkeley), and SYS3 (for System III, and V also, I suppose). Does anyone know how to fix up uc.c? The differences on umodem have to do with how you tell the system to kill echo, go to 8-bit transmission, etc. But all these calls are after the printf, so why don't we even see the sign-on message? (last-minute thought: maybe the output buffer is not getting flushed). I suppose I could hack up uc.c and put in the same things umodem has, but if someone else has already done it, I would appreciate a copy. Also, it should be added to the archives.
