have u heard of Genius FlexV 56K ?
well it is an internal modem, and I was using it with my P100, on ATC1000+
board, and when I no more needed a proxy, I started using my 486/dx 33 as
NAT
and this modem is working in this machine too, and dont say external modem
will out perform internal, I find it the other way, and internal modems
perform
better for me, since external modems have to depend on the serial port, but
internal ones will come with a serial port which will be matching for the
modem,
you might have seen only modem half cards or cnr modems, or even pci
internal modems
try an isa internal modem which has jumper settings, and use it you will
never regret it
