The rule below will allow you to issue commands to EDI port like this:

• Input command on EDI serial port: connect,101,103

- Generates internal command $CALL L101 L103

• Input command on EDI serial port: disconnect,101,103

- Generates internal commands $C L101

tmp 0 "%scutf(%edi,\,,0)"
tmp 1 "%scutf(%edi,\,,1)"
tmp 2 "%scutf(%edi,\,,2)"
if %scmp(%tmp(0),connect)
 $CALL L%tmp(1) L%tmp(2)
 stop
endif
if %scmp(%tmp(0),disconnect)
 $C L%tmp(1)
endif
