According to the ROM Kernel Manual, the serial device can be set to any
baud rate from 110 to 292000.  Additionally, "Although baud rates
above 19200 are supported by the hardware, software overhead may limit your 
ability to ``catch'' every single character that should be received.  The 
Output data rate, however, is not software dependent."  You're probably
trying to talk to your keyboard at the wrong baud rate, or something.
Have you tried messing around with the settings in Preferences?
