INT 14,2 - Receive Character from Communications Port
AH = 02
DX = zero based serial port number (0-1) (0-3 for AT)
on return:
AH = port status (see INT 14,STATUS)
bit 7 = 0 if successful
bit 7 = 1 if call failed
AL = character received if call was success
- INT 14,3 should be used to determine the actual cause of
the error since the time-out bit of the status register is
always set during an error on this call
- uses hardware flow control
