Set the send/receive area within the above ranges.
A data length of 1,000 words is valid only when the remote node supports it. If the
remote node can only return 256 words, any data greater than 257 words is not
guaranteed.
The PC Card Unit supports a data length of 1 to 997 words for the SEND(90)
instruction, and a data length of 1 to 1,000 words for the RECV(98) instruction.
8-1-4 Instruction Status
Status information for executed SEND(90), RECV(98), and CMCR instructions
is reflected in the SR Area of the PC as instruction execution flags and instruc-
tion response codes.
The following two instruction execution flags are used:
Instruction Enabled Flag:
ON (“1”) when the SEND(90), RECV(98), or CMCR instruction can be executed.
Instruction Error Flag:
ON (“1”) when the SEND(90), RECV(98), or CMCR instruction has terminated
abnormally.
If multiple instructions are to be used, always make sure that the Instruction
Enabled Flag is ON before executing the next instruction (i.e., perform exclusive
control).
