Device number for sending out stimulus ID values if stimulus flag 2 is set (see FLG).

Port values are:
      1 = COM1:  serial port 1
      2 = COM2:  serial port 2
    100 = LPT0:  parallel port (default)
      -1 = digital output port (see CIGAL help for INIT)

Note: Before using either serial port, the port parameters must be set (see CIGAL help for COM1 or COM2). Before using the parallel port you must initialize it (Parallel port).
