It works slipping in to my office, which is set up with a 14.4 modem, using kermit, and I can access various local bbs's at 26k and 28k to another lab. The boca product code is MV.34IM . The dmesg looks like "sio2 at 0x3e8-0x3ef irq 5 on isa sio2: type 16550A". I do believe that the board uses emulation since the large chips on the board are labeled "rockwell" and the <A HREF="http://www.boca.org/">; Boca WWW </A>site indicates that they use emulation on a similar 14.4 modem. No info on this one in the web page that I could find. Boca seems to feel that the cost savings justify not using the 16550. I wish they had the courage to label their packages with this info so dummies like me wouldn't get suckered in like this. Thanks again.
