I am looking for any commercial device that will help me,
including a single chip computer, microcontroller, single 
board computer.  I am trying to avoid using a 3 board system.

I want a device which can input RS-232 (or 422) data at a
low baud rate (1200-9600), do some simple processing, and
output (ouput ONLY) RS-422 at 250,000 bits/sec.  

My first choice is a single board computer, but I can't 
find any that has 2 serial ports, and can output at 250k.

My second choice is to build one, using a single-chip
controller with a serial port (8051 maybe), and a high
speed UART.  Of course, a single chip with 2 serial ports
would be better.

Any help or ideas would be appreciated.
