1. you must be using windows.

2. no, it doesn't limit it to  19200

3. i have a 2400 baud if you want to trade.

Selling the modem would be kind of stupid.
Upgrade the serual chip in your controller card fron 8250 Uart to 16550
uART. If the cip is soldered, then jusy buy a LAVA high speed serial
card for twenty-five bucks, plug it in, and hook your modem up to that!

	If it's an external modem than it does not require Windows.  One model
of internal USR modems require Windows, but not any of the others.

	It's most likely that the serial port in the 486 has only a 16450 UART
in it, in which case the original poster may run into comm overruns
when the serial port rate is set to more then 19.2kbps.  Of course,
new serial ports with 16550 UARTs on board only cost about $25.

Selling it would be kind of stupid, when all you have to do is upgrade
your controller card serial chip to 16550 uART, or, if the chip is
soldered, just get a high speed LAVA serial card, and plug the modem
into that.
Either solution costs just twenty five bucks, or less.
Haven't you ever heard the word "upgrade" :-)

I should have probably pointed out that the machine in question is a 
DEC notebook, not a desktop model.  Therefore upgrading the IO card wouldn't 
be as easy or cheap.  However if I'm wrong on this, I'd love to be corrected 
by anyone who knows more about these things.

Thanks
