When the Communications Port Enabled Flag for port 7
is ON, and SEND(090) is not being executed, the trans-
mission execution program will start when execution
condition CIO 000001 turns ON.
Input CIO 120002 remains ON from the start of
RECV(098) execution until completion.

A total of 16 words of data beginning from word A100
at network number 3, node number 32, unit address 0
(the PC) is received at word CIO 2000 onwards of the

word A202 turn OFF even when the PCMR(260) instruction is being executed
using the ports corresponding to those flags.

Transmission Delays
The methods of computing the maximum time required from execution of the
SEND(090), RECV(098), and CMND(490) instructions until processing is com-
pleted are described in this section. These times, however, do not take transmis-
sion delay times on the network into account, so they may be increased depend-
ing on the conditions under which the instructions are executed.
