Code Operated Matrix Switch
12
The STATUS screen shows PORT NAMES, which
ports are LINKED to other ports, which links are
TRANSPARENT, (a transparent link does not honor
the Attention command), ACTIVITY (the presence
of buffered characters), and the ATTENTION
strings for each port.
L — Link
When the Code Operated Matrix Switch receives an
ATTENTION string followed by an
L and two PORT
NUMBERS, it attempts to set up a bi-directional link
between these two ports. If either of these ports is
already linked, the Code Operated Matrix Switch
sends a message to the port that issued the
command, indicating that the link was not made.
Otherwise, the two ports link and the Code Operated
Matrix Switch sends a message to the port that issued
the command, indicating that it made the link.
NOTE: Any port can issue the Link command, even
if that port is not one of the two ports being
linked. For example, Port 1 could issue a
command to link Port 2 and Port 5.
U — Unlink
When the Code Operated Matrix Switch receives an
ATTENTlON string followed by a
U and two PORT
NUMBERS, it attempts to break a bi-directional link
between these two ports (“unlink”). If these two
ports are not linked to each other, the Code
Operated Matrix Switch sends a message to the port
that issued the command, indicating that the unlink
was not made. Otherwise, the two ports will be
unlinked and the Code Operated Matrix Switch
sends a message to the port that issued the
command, indicating that the unlink was successful.
