>Look at e.g. Atmel's 89C51 (its clock can be up to 24MHz, so programming >its UART for 31.250 baud really simple). (Even you can do it with any >MCU from the MCS-51 family, take a look at the PAiA MIDI2CV). Well I'll be damned. On some of these MCU's it seems like the serial port was only included so you can program the damn thing. Terry Bowman, KA4HJH "The Mac Doctor"
