Prefix
A prefix is a subset of the preamble normally formatted to some
industry standard, i.e., it is represented by a specific ASCII code. An
example of a prefix is the STX (Start of Transmission) code.
IA Prefix = None*#
IB Prefix = STX
IC Prefix = SOH
Suffix
A suffix is a subset of the Postamble. Like the prefix, it is normally
assigned a specific ASCII code. Examples of suffixes are CR (Carriage
Return) and LF (Line Feed).
MA Suffix = None #
MB Suffix = ETX
MC Suffix = CR
MD Suffix = LF
