K:
least significant 2 bits of 6-bit message checksum
(Tables 50 and 51), most significant 4 bits are in the
vector word. See Section 8.8.7 for a description of
message checksums.
N:
message number (Table 51). See Section 8.8.8 for a
description of message numbering.
R:
message retrieval flag (Table 51). When this bit is set,
the pager expects this message to be numbered.
See Section 8.8.8 for a description of message
numbering.
S:
special format, (Table 51). In the numbered message
format, when this bit is set, a special display format should
be used. Spaces and dashes, specified by the host, are
inserted into the received message to ease reading of the
message. This feature may avoid the transmission of an
additional word on the channel. The actual format is
undefined in FLEX
and may be determined by the
manufacturer.
