usage: writeport id flg start duration value portnum

The WRITEPORT stimulus event causes a value to be sent to an external data port at the time specified by the START argument. The DURATION argument can be used to indicate a time delay until the next stimulus, but the DURATION has no meaning for the WRITEPORT operation itself. If the output port is a digital port, the value written will remain active on that port until a new value is written.

The PORTNUM argument specifies which data port will be writtten. CIGAL specifies external ports as:

PORTNUM:
    -1  - digital port
   100  - printer port
     1  - COM1 serial port
     2  - COM2 serial port
     3  - COM3 serial port
      ...
