INT 14,1 - Send Character to Communications Port
AH = 01
AL = character to send
DX = zero based serial port number (0-1) (0-3 for AT)
on return:
AH = port status (see INT 14,STATUS)
bit 7=0 indicates success
bit 7=1 indicates error, bits 0-6 indicate cause
- 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
