8.7.8.3
Alphanumeric Message
FLEX
alphanumeric messages are encoded using the
7-bit encoded alphanumeric character set defined in
Table 43. Characters are placed in codewords along with
additional information about the message as described in
Tables 44 and 45 and the following definitions. The 7-bit
characters of the message are designated lower case
letters a, b, c, d, etc.
Alphanumeric messages can be sent as fragments.
See Section 8.8.5 for a description of message
fragmentation.
Control characters that are not acted upon by the pager
are ignored in the display process (do not require display
space) but are stored in memory for possible download to
an external device. The ASCII character ETX (03H) should
be used to fill any unused 7-bit characters in a word.
Where symbolic characters (e.g. Chinese, Kanji etc.) are
being transmitted, special rules for fragment and message
termination are defined in Section 8.8.5.1.
Each 7-bit field, starting with the second character of the
second word in the message (first character of the second
word in all remaining fragments), represents standard
ASCII (ISO 646-1983E) characters with options for certain
international characters.
