PK-88 OPERATING MANUAL
3.3.5
Default Values
Most commands have initial values that the PK-88 assumes as defaults or values
suitable for the 'average case', or 'used most often.' These defaults are
stored in EPROM and loaded into RAM when the system is first powered up - or
when you give the RESET command.
3.3.6
Parameters, Arguments and Values
Some commands need additional information before they can be executed. This
type of command has 'parameters' or requires 'arguments.'
For example, the command FULLDUP has a Boolean (YES/NO) parameter:
The value that fills this parameter is either ON or OFF. You can also use
YES for ON and NO for OFF. You can also use 'T' to "toggle" the state of
the parameter.
When you type FULLDUP ON, FULLDUP is the command, ON is its argument the value
you want the PK-88 to use to execute the command FULLDUP.
Immediate commands such as ID have no parameters. Typing only 'ID' causes
the PK-88 to execute the command (if HID is ON).
Some commands such as CONNECT have optional parameters.
If you enter CONNECT without an argument, the PK-88 displays the current
status of the link.
However, if you enter CONNECT WXlAAA, the PK-88 issues the connect request and
tries to establish the link to WXlAAA.
Some commands such as MFILTER can use several arguments at the same time.
MFILTER accepts from 1 to 4 numerical arguments. You can type MFILTER 12 or
MFILTER 12, 26. Both are legal commands.
Three different types of parameters are used: Boolean, numeric, and text or
string,
Boolean Parameters
Boolean parameters have only two possible values: ON or OFF, YES or NO, or
EVERY or AFTER. When a parameter is Boolean, its two possible choices are
shown separated by a vertical bar. These values can be "toggled", or
alternately switched by typing simply 'T' after the command name.
Numeric Parameters
A parameter designated as 'n' is a numeric value. Numeric values can be
entered as decimal numbers, or optionally as hexadecimal numbers. When
entering a hexadecimal number, you must prefix the number you type with a '$'
character.
