This may be just the incongruous ravings of a total amateur but please help if you can. I am running a dec 11/73 under 2.9 and am having a problem with cu. The problem results from trying to port a file to a non-unix remote system (e. g. telemail). Because of overrun problems, I have written a short program which transfers a file by writing to the standard output a line at a time with a variable-length sleep at the end of each line. If I don't toggle cu so that it does this silently (no output at terminal from the the file transfer) I get garbage interspersed with a few correct characters. Otherwise the transfer works fine in the silent mode. The same goes for the standard cu file-transfer facility except that in the noisy mode the system eventually crashes with a "panic: timeout table overflow" message. If I attempt to kill cu from another port the processes die but garbages continue to dump to the offending port for a long time (several minutes) after ps says the processes are dead. I also find that if I start up cu with a tee to save a record of a cu session, the destination file has mostly unprintable garbage in it very similar to the garbage dumped at the terminal during a file transfer. I have talked to my friendly neighborhood guru about this and he theorizes it's a bug in the kernel, but doesn't have the time to deal with the problem. Has anyone seen this problem or am I just hallucinating??!! It is entirely possible that it has been posted on the net and I have missed it or am too stupid to recognize it. *** REPLACE THIS LINE WITH YOUR MESSAGE ***
