This command will read a byte from the RS232 channel given by channel according to the rules set using InitSer, and store the received byte in the variable output.

Example:

  'This program will read a byte from PORTB.2, and set the LED on if
  'the byte is more than 50. This can be used with the SerSend
  'example program.

  #chip 16F88, 8

  #define RecAHigh PORTB.2 ON
  #define RecALow PORTB.2 OFF
  #define LED PORTB.0

  Dir PORTB.0 Out
  Dir PORTB.2 In

  InitSer 1, r9600, 1 + WaitForStart, 8, 1, none, normal
