Does anyone know of a microcontroller with a lot of

anyone have any clues on how to connect say 16 or so
UARTS to a microcontroller?  Right now it is for my
curosity or something I would like to build for my
home, but maybe try to sell it.

This is where an FPGA-based microprocessor like Xilinx Microblaze would be perfect. You can create a system with as many UARTs as you want (limited only by logic capacity of the FPGA).

The uClinux port to Microblaze is pretty solid, and adding kernel support for numerous UARTs would be trivial.

See my website

for more info on microblaze uclinux.
