Technical Information
The following information is for technicians diagnosing
the system.
Baud-Bate Selector (Location 64268)
This setting controls the rate at which data can travel
through the serial port, used by a computer for diagnostic
purposes. This Location Code sets the initial baud rate
after the
CPU3
has been turned on or reset. Select the
appropriate entry from the following:
0 300 baud
1 1200 baud
2 2400 baud
3 4800 baud
4 9600 baud
5
19,200 baud (not used by the TCPU3)
Note: Entering any other number at this Location Code
will select the default setting of 1200 baud. Adding “128”
to this Location Code will prevent the CPU3 from adjust-
ing its baud rate in response to the TCPU3 program.
Trap Vector
64270 Trap-Address Offset.
64272 Trap-Address Segment.
Additional Monitor Commands
"xxxx:”
sets
the Segment Address to "xxxx" (it also
sets the Link Number for node commands).
“xxxxc=” sets
the Offset Address to “xxxx” (it also sets
the Physical Number for node commands).
"nL”
node command executes the command “n”
below and returns the line status.
The Commands
0 Take no action but report status.
1
Connect the specified
line to the specified link.
2
Disconnect.
3
Turn on the speaker relay.
4 Turn off speaker relay.
5 Turn on the single-link phone relay.
6 Turn off the single-link phone relay.
7 Create an active-list record if none already exists.
8 Delete the active-list record.
The status is reported as four characters,
abcd:
a = “+” (off
hook), “-" (on hook), “N” (no hybrid).
b = “N” (no input to “T”), “R” (resistor),
or “G” (ground).
= “V”
for

activated,
or “v” for not activated.
d = “A”
if the line is active, “a” if it is not.
