AlphaServer 800 OPA0 Doesn't Accept Input
I've tried reseting my session and swaping the cables. I rebooted it again and let OpenVMS come up and connected via TELNET and executed the following:
$ show dev opa0 /full
Terminal OPA0:, device type unknown, is online, record-oriented device, carriage
control.
Error count 0 Operations completed 98
Owner process "" Owner UIC [SYSTEM]
Owner process ID 00000000 Dev Prot S:RWPL,O:RWPL,G,W
Reference count 0 Default buffer size 80
Does anybody have any thoughts of what to try?

_What_ is connected to the OPA0 console port?
Which port is that? (How many does it have?)

If you shut down, so that you actually get a
">>>" prompt, does it work?
What, exactly, does "doesn't accept input"
mean? Characters put in don't echo back?
Commands don't work? ???

Re: AlphaServer 800 OPA0 Doesn't Accept Input
The console connection via COM2 does get a little weird, and switching and remaining on COM1 works rather better here. Here's a related discussion, and with some terminal settings and such:
http://labs.hoffmanlabs.com/node/995
If you haven't been swapping ports around on the box, then there may be a lower-level problem with the port or the console or such. Try power-cycling the box, but it wouldn't be a stretch to have some sort of a hardware problem on a box this old. Also look at reloading the SRM firmware, too.
And this also might not be the first time that a (I presume) Microsoft Windows box or a Windows terminal emulator has lost its place when performing serial I/O, either. Reboot the client.

Re: AlphaServer 800 OPA0 Doesn't Accept Input
However, it doesn't matter because even when OpenVMS is booted, it doesn't accept keyboard input either.

Re: AlphaServer 800 OPA0 Doesn't Accept Input
And you've tested this stuff? (Connect pins
2 and 3 at the far end of the cable?)

If you knew what mattered, then you probably
wouldn't be here.
Trying to decide between a hardware problem
and a software problem seems to me to be a
reasonable course. But if you don't care,

Re: AlphaServer 800 OPA0 Doesn't Accept Input
I found another connector and connected via the COM2 port and everything worked fine.
At this point I'm thinking it's a hardware issue with that COM1 port. Thanks for all the quick replies and suggestions!
