Toshiba SX 2000 - Manual (Page 54)

When using the above sample program as a part of entire application program,
set R0100 to ON in the main processing part at first. When a message is
received, R0101 (at normal) or R0102 (at error) comes ON. Then reset R0100
and carry out necessary processing for the received message. When the result
status shows normal complete (R0101 is ON), the received message has been
stored in D1100 and after.
When it becomes ready to receive the next message, set R0100 to ON again.
(3) Data send operation
The expanded transfer (XFER) instruction is used to send the message through
the optional communication card.

Operation:
When the input condition of the XFER instruction comes ON, the message
prepared in the registers starting with A is transmitted.
The execution status is monitored by B+1 as follows.
B+1 (Execution status): FIOOOO ^ Normal complete
FI0001 ^ During transmitting the message
FI0002 _ Communication busy (other receiving or
transmitting routine is under executing)
FI0003 ^ During the reset operation
FI0004 ^ Send time-out (see below)
FI0005 ^ Send message length error
(no trailing code in the source table)
