Thanks Mike! I'll give it a try.
Mark, Mike can do a better explaination, but I'll try.  The basic
objection to internal modems is that the manufacturer can buy cheap
chips and implement the UART+modem functions in a non-standard way,
emulating 16550 uart performance in a way that dos/windows can use, but
real os's can't use/configure/recognize. 
My problem was that my cheap computer had 16450's in it.  These probably
won't support V34 transfer rates with an external modem. I guess I
should have spent the extra money for the external modem and more for
another internal 16550 based comm3/4 card! 
Thanks again!
