(or transmission) and receive. The first
elements of the RS instruction specify the
transmission data buffer (S) as a head
address, which contains m number of
elements in a sequential stack.
The specification of the receive data area
is contained in the last two parameters of
the RS instruction. The destination (D)
for received messages has a buffer or
stack length of n data elements. The size
of the send and receive buffers dictates
how large a single message can be.
Buffer sizes may be updated at the
following times:
1) Transmit buffer - before transmission
occurs, i.e. before M8122 is set ON
2) Receive buffer - after a message has
been received and before M8123 is
reset.

Operation:
This instruction performs the direct control of
communications over FX and FX
adapters which connect to the left hand port of the
Main Processing Unit, i.e. FX
232ADP etc.

Data devices:
D8120 - Contains the configuration parameters for
D8122 - Contains the current count of the number of
D8123 - Contains the current count of the number of
D8124 - Contains the ASCII code of the character used
D8125 - Contains the ASCII code of the character used
Operational flags:
M8121 - This flag is ON to indicate a transmission is
M8122 - This flag is used to trigger the transmission of
M8123 - This flag is used to identify (when ON) that a
M8124 - Carrier detect flag. This flag is for use with FX

useful in modem communications
where only the lower 8 bits in each source or
destination device are used, i.e. only one ASCII
character is stored in one data register OFF =
16bit mode where all of the available source/
destination register is used, i.e. two ASCII
characters are stored in each data register.
