OK .

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,=20 Parity None, Stop bits 1, Flow control RTS/CTS.

2) I have managed to communicate with this settings = between=20 two COM ports on that NT box using a terminal emulation

program which supports serial=20 communication.

3) I set the SRM variable 'console' to 'serial'. = This affects=20 the behavior of Alpha box at start up i.e I didn't get

the SRM=20 prompt on graphics console untill I press Enter key, and I didn't = get the=20 ttyv0 after FreeBSD boots.

I steel have = other=20 ttyvs.

4) There is = another problem=20 which makes me CRAZY. Getty don't want to grab the serial port when I = set it to=20 "on"

in=20 /etc/ttys. below is the line from /etc/ttys.

= "ttyd1 =20 "/usr/libexec/getty std.9600" vt100 on = secure"

after kill -HUP 1 = or even the=20 system restart "ps -U root |grep getty" outputs nothing about = ttyd1.=20 But everything about

ttyvs = ;-))

My questions are

0) Why I get=20 the garbage on terminal when powering up Alpha box (Stage till the SRM=20 prompt)

1) Why I didn't get anything on = terminal after=20 booting from SRM prompt (I mean the whole kernel output)

2) Why the getty doesn't grab the = com2 port=20 ?

I'll be very thankfull If you'll answer. =

I'll be also thanfull if you'll not answer cause = then I'll=20 spend the time doing something esle instead of

I am having a very similar problem = with my=20 164sx. I've had this for a while but didn't have time to check = it=20 out. Serial output sill be fine if coming from kernel (kernel = messages=20 like root logins or cdrom messages). Anything else gets=20 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.
