   I am 'porting' the AST serial card driver (i386) to Titan TC-400 serial
   cards (i386).  The driver works, but when I try to set the baud rate to
   more than 38400 bps I get this:

   root@mui /a # wermit -l /dev/tty03 -b 115200
   ?unsupported transmission rate

   I guess this is because the driver uses the generic com driver code and
   the baud tables don't have entries for such high speeds.

The com driver has no `baud tables'; it simply calculates the correct
numbers from whatever baud rate you supply.  This is a deficiency in
