When the instruction input is ON, one set of message which is stored in the

source table (from start character to the trailing code) is transmitted through

the link port. The execution status is stored in the status flag.
The instruction input must be kept ON until the transmitting operation is
complete.

Example:

Source designation

Transfer size

Destination designation

D0010

HOO
