PMCR(260) will execute the communications sequence specified in C2 using
the logical port specified in bits 12 to 15 of C1 and the physical port specified
in bits 8 to 11 of C1 for the unit address specified in bits 0 to 7 of C1.
If a symbol is specified as the operand for a send message, the number of
send words specified in S and beginning from S+1 will be used as the send
area. If a symbol is specified as the operand for a receive message, receive
data is placed in memory staring with R+1 and the number of words received
is automatically written to R if the transmission is successful.
If the transmission fails, the data (R+1 onward) set before PMCR(260) was
executed will be read from the receive buffer and stored in the R+1 onward
again.
