HANDSHAKE PROTOCOL
Rs422 serial line has no handshake protocol.
It means that if you transmit more than 2 / 3 KBytes of data at a time it’s strongly recommended to insert a short
delay (1 or 2 msec) between transmission of each character, in order to avoid printer errors during data receiving;
alternatively software XON / XOFF.handshake mode may be used.
Connection to personal computer may be done in different ways based on used converter.
