Text Or String Parameters - Advanced Electronic Applications PK-88 Operating Manual

PK-88 OPERATING MANUAL
In using hexadecimal notation, you must prefix the number you type with a '$' charac-
ter.
The PK-88 displays numeric parameters which set special characters in hexadecimal for-
mat. 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 ex-
ample:
For numeric parameters in the range 0 to 255, arguments 'ON' or 'Y' set the value of
the parameter to their ROM default values. Arguments 'OFF' or 'N' set the value to 0
(zero).
Baud-rate parameters can use arguments UP (U) or DOWN (D) to select the next higher
or lower radio (HDLC) link or terminal baud rate.

Text or String Parameters

A text parameter such as the argument or 'message' for CTEXT (your 'connect' mes-
sage), can be typed in upper or lower case.
o A text parameter can include numbers, spaces, and punctuation.
o The text is accepted exactly as you type it.
Some commands require call signs as parameters. The parameters may be any string of
numbers or letters, up to six characters; character strings are used to identify stations
sending and receiving packets.
A call sign can also include a numeric extension or substation identifier (SSID). These
extensions distinguish between two or more stations with the same call (such as a base
station and a digipeater).
The call sign and any required extensions or SSIDs are entered and displayed as 'call-n',
e.g., 'KX1AAA-12', or 'WX1AAA-1'. If an SSID or extension is not entered, the system
assumes an SSID of '0' (zero). The zero SSID is not normally displayed by the PK-88.
Some commands have parameters which are really lists of call signs:
o CFROM, MFROM, MTO and DFROM commands allow you to specify from one to
eight call signs for selective or restrictive operations.
o You must separate multiple call signs with blank spaces, commas or tabs.
The following examples will help you understand these explanations.
o BEACON EVERY|AFTER
The BEACON command requires an argument.
o You must specify either EVERY or AFTER (abbreviated E or A), and an argument
which is chosen from a range of values.
$1B - (1 × 16) + (11 × 1) = 27 (decimal)
$120 = (1 × 16 × 16) + (2 × 16) + (0 × 1) = 288 (decimal)
