USR Modem Problem

[Tom Smith]

ENVIRONMENT
FreeBSD 4.8
Kermit 8.0.206
US Robotics "Python" (OEM ,56k, V.90, Data/Voice/Fax)

QUESTION
Are there FreeBSD specific modem settings required for dialout to work 
(even from Kermit)?

SITUATION
I installed an internal USR "Python". The modem is jumper configurable 
and set to use COM2 (IRQ 3, I/O 2F8).

Initially, I had the mobo onboard COM1 enabled. I could connect to the 
modem via Kermit but when I executed a command (like ati4) the output 
wouldn't automatically scroll onto the screen. I would have to hold down 
the space bar for the output to appear. For example, each time I pressed 
the space bar another letter of the output would appear on my screen.

I disabled the onboard COM1 and now when I run ati4 the output scrolls 
on to the screen automatically. But now, it's telling me there's no 
dialtone when I run atdt<number>. I know this line works as I have 
another phone hooked up to it. When the modem reports "no dialtone" the 
phone line also goes dead until I close the connection to /dev/cuaa1. I 
also know the modem to work as I borrowed it from a RedHat 8/HylaFax server.

I was hoping to be able to use an INTERNAL modem on this server. 
However, is it wiser to use an EXTERNAL? (I also have two USR Courier 
V.Everythings sitting idle.)
