Are you doing it just for the money?

The third serial port is going to be a problem.
Do you need a usart for this or could you bitbang the data from a pio?

Maybe some pointers here..
PIC RS232 IO
PICMicro Serial Routines

Maybe

8051 based so you should be able to find a c compiler

Or then again,

If you prefer the embedded Linux approach.

Edited to show more ports than I'd thought...

I've bought stuff from Pang's before, never had a problem with them.

Essentially it needs to take serial input from 2 sources and output this to another serial interface only when this interface is connected.

I'm thinking this may be out of the league of PIC as it'll need to access external RAM and format the text for output, in that case anyone got any other suggestions. Ideally needs to be cheap without moving into miniature PC market. Also if it could run c code that would be great.

What about a Z80 or Atmel AVR?
