A.2.2 Default Values
Almost all commands have initial or default values that are loaded
when the PK-232 is first turned on. The PK-232 assumes these default
values to be best suited for the "average" amateur station operation.
There is no rule that says "you must keep the defaults". You can (and
should) change the default values as required for your individual
operating needs, type of equipment, or local customs.
A.2.3 Modes in which the command is used
Many commands work only in a specific operating mode such as packet.
Others commands function in all modes. The second line of the command
description tells the mode or modes in which the command functions.
A.2.4 HOST Mode Abbreviations
If you are a computer programmer and wish to write an application for
the PK-232, you may want to consider using the HOST Mode. Information
on HOST Mode is available in the PK-232 Technical Reference Manual.
A.3 Parameters and Arguments
If a command requires Parameters, the type of parameter is indicated
after the command name as well as its default value. Three different
types of parameters are used: Boolean, Numeric and Text or String.
A.3.1 Boolean Parameters
Boolean parameters use one value out of a choice of only two possible
values, such as ON or OFF, YES or NO, or EVERY or AFTER. Boolean
parameters can also be toggled with an argument of "TOGGLE" or "T."
This is useful, for example, in the case of RXREV and TXREV.
A.3.2 Numeric Parameters
A parameter designated as "n" is a numeric value. Numeric values can
be entered by typing them in familiar decimal numbers, or optionally,
in hexadecimal numbers (base 16).
When using hexadecimal notation, you must type a $ in front of the
number to tell the PK-232 that this is a "hex" number.
Here's a brief explanation of "hex" numbers:
o The "digits" of a hex number represent powers of 16 in the same
manner as the powers of 10 represented by a decimal number.
o The numbers 10 through 15 are indicated by hexadecimal digits A
through F. For example:
$1B = (1 x 16) + (11 x 1) = 27 (decimal)
$120 = (1 x 16 x 16) + (2 x 16) + (0 x 1) = 288 (decimal)
For numeric parameters the arguments "ON" or "Y" set the parameter
value to its default. Arguments "OFF" or "N" set the value to 0.
Baud-rate parameters can use arguments UP (U) or DOWN (D) to select
the next higher or lower baud rate.
