Table C-1. Labels Used in S-Registers
Label Description
Register: The S-register is identified following this label. Note that
the names for S-registers 1 through 9 may be typed as
two-digit numbers with leading zeros, if desired, for
readability (for example, S01 is equivalent to S1).
Description: The purpose and use for the S-register is explained
following this label.
Range of Values: The range of values that may be assigned to the
register is explained following this label. The units for
the value may be as follows:
■decimal — a one- to three-digit decimal number.
Decimal numbers are typically used to represent a
count, seconds, or fractions of a second.
■ASCII — a one- to three-digit decimal number that
represents the decimal equivalent for an ASCII
character (see the ASCII Character Set; Table E-7
on page E-11).
■hexadecimal — a two-digit hexadecimal number
used to represent the contents of a bit-mapped
S-register. Bit-mapped S-registers are not usually
set by entering a complete value for the register, but
are set one or more bits at a time by various AT
commands. Hexadecimal digits include the decimal
digits 0 through 9 and the letters A through F.
