Examples:
  rs232-gen -b 115200 -d 100:0xFF,0x00 -d +100:0xFF,0x01
  rs232-gen -b 9600 -f 4000000 -c 100:Test\ String

Example stc file:
  # example.stc
  load s example.cod
  frequency 4000000  		# must match the freq. used by rs232-gen
  node uart_test     
  load c uart_stim.txt		# the output from rs232-gen
  attach uart_test rs232_stimulus portc7 # portb1 for 62x
