Ok...I'll try to make this description as painless at possible!  :-)

I have an old 9600 baud modem off the back of a FreeBSD box I set up at
work.  I have the modem setup to answer the phone and give a login
prompt.  This was no problem.  I can dial in and get the prompt
everytime.

The problem arises _after_ I hit the 'enter' key, following the
password.  I get a few characters of the login message (copyrights, etc)
then my screen goes to pot.  

I am making an educated guess that there is a parity flip occurring
on the line from the time I hit enter after the password to the time the
actual login is processed.  Whatever I type at the remote end is echoed
back cleanly and is executed properly but the 'text' coming back down
the line is complete garbage.  I have tried dialing in with _every_
conceivable and supported bit scheme.

I would post my gettytab and ttys entries, but I'd have to drive a fair
distance to login at the console...;-)  In any instance, the ttys entry
should be fine set as 'dialup', and my std.9600 entry is the stock,
generic entry.  I am highly certain that it is set to NO PARITY.

I am beginning to pull my hair out.  My uucp connection can't even
resolve a "Shere" when logging in.

Hardware of interest:  ATI 9600 modem, Soyo P5-75 PCI integrated
mainboard (IDE, serial, etc)

I originally suspected a flaky UART but then I remembered that I had
used that same port earlier in the week with another device and had no
problems.




At any rate, I need to get this working ASAP and I have completely
exhausted my local resources.  I suspect I'm rambling now.  Mental
exhaustion can do that to you. :-)


Any help is greatly appreciated!
