High speed serial port expansions

I would say YES it would make a difference. Most add on serial ports (like say surf squirrel) have high speed buffers built in and allow much greater speeds that native port.  Dont know if the games support them or not, but if the game has a prefs mode for the networking you should be able to select the device manually..

baud bandit is a specific driver. There are many drivers out there with high speed, Surfsqurriel device, duart.device from Multiface, Gvp i/o device etc etc
