Accessing serial console of Fire V210

[Konstantin Saurbier]

Hi,

i've bought a used Sun Fire V210 and wanted to install FreeBSD 8.0 onto it.
If I connect to the serial management port (ALOM) the input is severely broken.
The output of the server, ALOM, OBP and FreeBSD install-dvd is ok, but my input
is garbage. It is no direct 1-to-1 key mapping, but rather random mixup:

Try		Input			Response
1		111111111111	531?1?5351q1
2		111111111111	3±5??3?1?1?q
3		111111111111	?��?1?1????3

Serial settings: 9600, 8N1, no flow control. I tried different computers and programmes
(cu, tip, kermit, minicom, screen, zterm and hyperterm).

Is it a hardware error of my usb/serial-dongle?
I is a Prolific Technology PL2303 based device:

ugen0.2: <Prolific Technology Inc.> at usbus0
uplcom0: <Prolific Technology Inc. USB-Serial Controller, class 0/0, rev 1.10/3.00, addr 2> on usbus0

Any hints or directions?

Best regards,
Konstantin Saurbier
