Messages sent by PageGate software include more information than just the message text. The Sender's Name (can be optionally disabled) and the Subject of the message (optional). A colon ( : ) separates these fields.
Most pagers have a limited character set usually consisting of upper and lower case letters, numbers, and some symbols (periods, commas, dollar signs, exclamation points, etc.)
Non-printing characters such as carriage returns, line feeds, and tabs can optionally be removed from a recipient's messages.
If the Reliapage feature is enabled, messages that are split into a series of messages will include the numbering index, i.e. 1 of 3, 2 of 3, 3 of 3.
