I've got a weird problem that I hope someone can shed some light on. I've got a SparcStation I, Telebit T2500 modem on ttyb, and SunOs 4.1.1. The modem is used for both incoming and outgoing calls. What happens is that every once in awhile the system is left with the getty running but it doesn't have DTR raised. The problem can be "fixed" by executing: ttysoftcar -n /dev/ttyb kill PID_of_getty_running_on_ttyb The modem is completely functional for outgoing use but the telebit doesn't answer if DTR is not raised. "ttysoftcar -a" is run from rc. Here are my device files: crw------- 1 uucp 12, 129 Mar 27 10:49 /dev/cua0 crw--w--w- 1 root 12, 1 Mar 27 09:25 /dev/ttyb Here are my telebit register settings......... ATN?
