Then again it might be related to your hardware. I remember the days of the 486. I had some boards with onboard 8250 UARTS, some with 16450 UARTS, and Some with an external 16550 UART. The type of uart is going to be good info to know. If your using an 8250 then 9600 (I think) is the max you will get out of the port. If you have a 16450, you can get about 19200 (not 100% sure on this one) from the controller. And if your lucky enough to have a 16550 UART, then you can get speeds up to 230,400 bps. This is all going to depend on the serial controller. You should be able to use "dmesg | grep sio" to determine what kind of hardware you are running.
