APN
Cellular Access Point Name (obtained from your cellular network provider)
argument
Part of a procedure call (or command execution).
array
A group of variables as declared in CRBasic.
ASCII/ANSI
Abbreviation for American Standard Code for Information Interchange / American
National Standards Institute. An encoding scheme in which numbers from 0-127 (ASCII)
or 0-255 (ANSI) are used to represent pre-defined alphanumeric characters. Each number
is usually stored and transmitted as 8 binary digits (8 bits), resulting in 1 byte of storage
per character of text.
asynchronous
The transmission of data between a transmitting and a receiving device occurs as a series
of zeros and ones. For the data to be "read" correctly, the receiving device must begin
reading at the proper point in the series. In asynchronous communication, this coordin-
ation is accomplished by having each character surrounded by one or more start and stop
bits which designate the beginning and ending points of the information. Also indicates
the sending and receiving devices are not synchronized using a clock signal.
AWG
AWG ("gauge") is the accepted unit when identifying wire diameters. Larger AWG values
indicate smaller cross-sectional diameter wires. Smaller AWG values indicate large-dia-
meter wires. For example, a 14 AWG wire is often used for grounding because it can carry
large currents. 22 AWG wire is often used as sensor wire since only small currents are car-
ried when measurements are made.
