I do it on both qbus MVII and MV3100 (use the DB25 Luke, it's a comm
port!).  The "however" is I'm running VMS should be the same hardware
wise.  teh modems used are USR 14.4 external (they were free).

Most if not all of the 3100s have one DB25 that is a full handshake comm
port.  Someone off list I used to know uses a VS2000 running ultrix to 
do address majik to an isp from their local subnet.

I hand made my cables so I can't help on what ones are correct.
