OK .
To make it more algorithmic ;-)
0) Hardware AS200 2 COM ports, and graphics card.
1) I Use WinNT as terminal , COM1 Baud rate 9600, Data bits 8, Parity None, Stop bits 1, Flow control RTS/CTS.
2) I have managed to communicate with this settings between two COM ports on that NT box using a terminal emulation
program which supports serial communication.
3) I set the SRM variable 'console' to 'serial'. This affects the behavior of Alpha box at start up i.e I didn't get
the SRM prompt on graphics console untill I press Enter key, and I didn't get the ttyv0 after FreeBSD boots.
I steel have other ttyvs.
4) There is another problem which makes me CRAZY. Getty don't want to grab the serial port when I set it to "on"
in /etc/ttys. below is the line from /etc/ttys.
"ttyd1 "/usr/libexec/getty std.9600" vt100 on secure"
after kill -HUP 1 or even the system restart "ps -U root |grep getty" outputs nothing about ttyd1. But everything about
ttyvs ;-))
My questions are
0) Why I get the garbage on terminal when powering up Alpha box (Stage till the SRM prompt)
1) Why I didn't get anything on terminal after booting from SRM prompt (I mean the whole kernel output)
2) Why the getty doesn't grab the com2 port ?
I'll be very thankfull If you'll answer.
I'll be also thanfull if you'll not answer cause then I'll spend the time doing something esle instead of
playing games with serial ports.
But better to answer ;-))

Subject: Re: Serial connection
I am having a very similar problem with my 164sx. I've had this for a while but didn't have time to check it out. Serial output sill be fine if coming from kernel (kernel messages like root logins or cdrom messages). Anything else gets skrewed!

I think you are using a wrong baud-rate for the serial connection.I have to use 9600 at mine to get correct output.AlexTo Unsubscribe: send mail to majordomo@FreeBSD.orgwith "unsubscribe freebsd-alpha" in the body of the message
