Not all that easy... Most paging companies implement the Telelocator
Alphanumeric Protocol (TAP).

Basically you have two choices, the Automatic or the Manual entry. You can
see the Manual form by connecting with Hyperterminal or a similar app, and
entering M<CR> when you see the 'ID=' prompt. You may need to send a couple
of CR's first to get the prompt.
The problem with the manual protocol is it is not uniform, and the text to
prompt you for the pager id and message varies from company to company. The
automatic is more uniform, but you need to build blocks with the proper
checksum or they will be rejected.
In either case, you will need to carry on a dialog with the terminal once
you connect to establish the protocol and to handle retransmit requests or
error messages.
