 I should point out that the above mentioned products ONLY work for
terminal emulators that use INT 14H as means of accessing the RS232 port.

99% of all serial terminal emulators written for the IBM PC directly
address the 8250 (16450) Uart chip. This is because INT 14H does not
provide interrupt driven access and thus can only support baud rates below
2400.

If you have a terminal emulator that supports 9600 baud the chances are
that it will not run with any of the above mentioned programs.

I only know of one program that can handle emulators which directly address
the Uart chip. BWCOM from Beame & Whiteside Software Ltd. loops back the
8250 chip and pass the information to the network via TELNET. It emulates a
Hayes modem interface to the terminal emulator.

P.S: I have the Bridge NetBios board and I've checked it out.
