You want to set the serial port rate somewhat higher than the modem rate,
as compression in the modem will help in many cases. A 16550A UART will
operate fine at 115200. 57600 should be fast enough for a 28800 modem
also. If you have a 16450 UART, you will probably not get better than
19200 without errors (sometimes even 9600 can give errors with these).
