Morning all ...

        I'm trying to get my serial console to work on my desktop, and
appear to be failing miserably at even just getting it to accept a 'getty'
serial connection, let alone serial console ...

        First, my X/mouse runs on /dev/ttyd1 ... if I startx, my mouse
does work, but X hangs *very* quickly.  Based on this, I know that
/dev/ttyd1 does work, at least for a short time.

        Now, to confirm ... a NULL modem cable *is* pin 2->3, 3->2, right?
rx->tx, tx->rx?  I've tested the cable using a multi-meter, just to make
sure that it is doing what I expect ...

        If I plug my cable from /dev/ttyd0 -> /dev/ttyd1 on the same
machine, run getty on /dev/ttyd1 and use kermit to connect to /dev/cuaa0,
I get no response back, which is why I'm wondering about sio ...

        I've also tried connecting my serial port on my laptop to both
/dev/ttyd0 and /dev/ttyd1, and run getty, and that doesn't get any login
prompt either ...

        Since, albeit briefly, I know that /dev/ttyd1 does work when X
starts up, I'd expect that getty would give me a login prompt if I enabled
it on that port, no?

        I'm running -CURRENT as of Feb 27th, and am just about to upgrade
again ... dmesg shows my sio devices as:

sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
sio0: type 16550A
sio1 at port 0x2f8-0x2ff irq 3 on isa0
sio1: type 16550A

        Which look right to me ...

        I've scan'd /usr/src/UPGRADING to see if there was something in
the past that I might have missed concerning sio, but couldn't find
anything ...

        And, sio is defined in my kernel as simple 'device sio' ...


Thanks ...
