Sean,

If you're trying to get the GPI status, I've figured this out in the
past.  Try this FN:

CLEAR LOCAL MODE
LOCAL FN CheckGPI(port)
  IF port = _printerPort THEN offset = 0 ELSE offset = 2
  serParams& = FN GESTALT(_"ser ")
  LONG IF serParams& AND 5                        ' modem and printer
port gpi available
    gpiState = (PEEK([_SCCrd]+offset) AND 8) <> 8
  END IF
END FN = gpiState

Happy Computing...
