OK .=20
To make it more algorithmic ;-)
0) Hardware AS200 2 COM ports, and graphics card.=20
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=20
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. =20
"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=20
ttyvs ;-))
=20
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.=20
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 ;-))=20

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 =
