Hi, I'm having some problems with serial terminal. I'm running 4.1-release on p166mmx (asus tx97-e mb) with dec vt220 on first serial port. I have it configured as a system console (boot.config -h). Im using 3 wire serial cable (db25-db25 2-3 3-2 7-7 and pins 8 and 20 (iirc) wired together on pc side to provide DCD signal). This seems to be working ok for a few days, but after a period of time i cannot send any data from the terminal to the pc (the terminal works ok, if i turn on local echo i can see chars appear). Usually i have shell running on vt220 all the time. If i kill this shell login prompt appears but i cant send my login. If i kill the getty a new spawns but the situation remains the same. Then i tried turning off the getty in /etc/ttys doing init q and then re-enabling the getty and doing the init q again. But when i do this no gettys appear. Not even on the local consoles. Like init is completely ignoring the HUP signal.. (i tried kill -1 1 instead of init q - it does not help). System messages however still continue to appear on the terminal. I wanted to test the connection with minicom but it says permission denied when accessing /dev/ttyd0, even when running as root. lsof does not report any processes using /dev/ttyd0. If i reboot the machine everything starts to work again. But since this is supposed to be 24/7 box i wouldn't like to reboot it every week or so... Did anyone have similar problem or has any idea what could be wrong? Greg To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
