Note In order to execute the SEND(192) instruction properly, it is necessary to pre-
pare a program on the host computer so that the host computer will process the
data that the host computer has received.
The RECV(193) instruction enables data from the host computer to be written to
the memory areas of the local PC.
When the RECV(193) instruction is executed, the CV-mode command
"MEMORY AREA READ" (command code 0101) will be sent to the host comput-
er in the following command block format.
