Serial Port Monitor Commands
Summary: The TClV’s built in monitor program responds to one-letter commands and hexadecimal
numbers. The principal commands are shown below in bold and quotes (i.e.: “X”) variable
values which can be input with commands are not in bold and are outside quotation marks.
The quotation marks are never part of the command or variable. An example of each com-
mand is given along with an explanation of its use.
These commands are available to any terminal or computer with a communication program.
They are used by the TCIV diagnostic program for the personal computer to accomplish more
extensive diagnostic functions.

Set the reference address to the value defined by the hexadecimal input aaaa.
Use to establish communication with a port (e.g.: 5= or
FOOO=)
Store bytes bb and cc in memory, starting at the reference address.
Use to change a value in RAM or EEPROM (e.g.: 5.E5. )
CPU must be switched to ENable to change EEPROM.
Example: To set the Monitor Lock (Location Code 64100 which is FA64 in
hexidecimal notation) to zero, enter
“FA64=0.0.”
Display the byte from the reference address and increment the address.
Halt the TCIV program (Location Code
64100
must have been set to 0).
Restart the TCIV program.
Send the data block (aaaa to dddd) to the serial port in the
INTEL hexadecimal format (Use to save an EEPROM Image.)
Data block includes all data from the reference address (aaaa)
to the ending address
(dddd) .
Receive a file in the INTEL hexadecimal format and store it until the
End of File command is received. (Use to load an EEPROM image.)
Output byte (ee) to the port defined in the reference address.
Input the byte from the port defined in the reference address.
Call a function at the reference address.
Parameter pppp is an optional hexadecimal value for use by the function
located at the reference address.
G means hold down the control key and press G.
(e.g.: OOOO= G will reset the TCIV; reference address 0000 contains the
reset function and no parameters were required.
00005 = G will call a TCIV function that computes and reports the TCIV
checksum value.)
Move the display cursor to the left margin of the next line and print the
current reference address.
