I have 3 different types of motherboards running FreeBSD 4-STABLE all in various states of cvsup but none older than 2 weeks ago. Using a null modem cable from one of them I can connect to each of the serial ports and get a login prompt as per what I have for ttyd0 in /etc/ttys: ttyd0 "/usr/libexec/getty std.9600" dialup on secure however, if I connect to them from a Cyclades T2000 terminal server using a cat5 patch cable and a RJ45-DB9F modular adapter I can't type anything in but I do see output (ie. from syslog). The most bizzare thing is if I reboot with: set console=comconsole in /boot/loader.rc it works fine with the Cyclades...that is, booting up, I see: sio0: type 16550A, console rather than: sio0: type 16550A So what is it about explictly setting sio0 to be the console that changes the serial line discipline? Connecting with a regular null modem cable seems to be unaffected in either case. Adi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
