Transmitting

To transmit a message, create the message, attach the address of the recipient
and then send it to the LES. The address of the recipient in the Inmarsat C
system is his telex number, for transmission via landline, or MES Inmarsat
Mobile Number (IMN), when transmitting to a ship.
The message can be one you've just prepared or one stored on a floppy disk.
(Messages cannot be transmitted by direct keyboard input.)
