According to the Keyspan's web pages, USA-28's advantages over USA19HS 
to mention, include 1 Mbps data rates (230 Kbps for USA-19) and two 
serial ports (one for USA-19). I don't think, however, your serial 
communication problem is likely to be resolved with USA-28...

Do you run UHFA.EXE under Windows 98? When I upgraded my Virtual PC 
from ver 6 to ver 7, I experienced a  trouble on serial communication 
under Windows 98 (second edition), which were difficult to describe 
here, while Windows NT 4.0 was OK. I gave up further investigation, but 
serial port still does not work under Windows 98 on my Virtual PC 7. 
Why not try for running UHFA.EXE under DOS or Windows NT 4.0? Maybe 
worth checking.
