PK-88 OPERATING MANUAL

MEMORY

n
Parameters:
The MEMORY command permits access to memory and 1/0 locations.
To use the Memory command:
⇒ Set the memory address into the ADDRESS command.
⇒ Use the MEMORY command without arguments to read memory locations one after another.
⇒ Use MEMORY with one argument 0-$FF to write to memory locations. After each MEMORY
command, the PK-88 adds 1 to the value of the ADDRESS.
PK-88 RAM locations are $8000-$FFFF. ROM begins at $0000.
The MEMORY command increments the ADDRESS counter by 1 each time MEMORY is typed.

MFILTER

Parameters:
Use MFILTER to select characters to be 'filtered,' or excluded from monitored packets. Parameters
n1 n2
, , etc., are the ASCII codes for the characters you want to filter. You can enter up to four
characters in either hex or decimal.
The default value $80 filters all received control characters except <CTRL-J>, ($0A), the line feed,
<CTRL-M>, ($0D), the carriage return, and <CTRL-I>, ($09), the HORIZONTAL TAB.
Use MFILTER selectively to remove specific characters from the data stream to the terminal or
computer. Here are typical applications.
⇒ To prevent a <CTRL-L> character from clearing your screen, set MFILTER 12.
⇒ To eliminate <CTRL-Z> characters, which some computers interpret as end-of-file markers and
some terminals interpret as a Clear Screen command, set MFILTER 26.
⇒ To eliminate <CTRL-G> characters, which beep your computer or terminal, set MFILTER 7.
MFROM all,none,yes/no call1[,call2..]
Parameters: call
MFROM uses arguments to determine how the PK-88 monitors the packet channels and displays
information – which stations' packets will be displayed and which stations' packets will be masked
or hidden. MFROM is set to 'all' when you start the PK-88 for the first time.
Type

MFROM

to display the ALL/NONE/YES_list/NO_list status of station call signs whose packets
will or will not be displayed. You can use the abbreviated command form or mnemonic:

the PK-88's memory and I/O locations, or to read values stored at a specified
address.
