If you're trying to run UMODEM on 4.2, you'll have to alter the alarm signal handling. I wrote the original code assuming standard V7/4.1 signal interruption handling (i.e. the read call returns with a -1 if interrupted). Good ol' 4.2 doesn't work that way (it normally continues the read) so you'll have to use longjmp's or some other mechanism to compensate... --Lauren--

From: Doug Kingston <dpk@brl-vgr> The recommended technique is to use the select() system call. -Doug-
