A little while ago I poeted a message asking if anyone had an alpha pager program. My thanks to all that responded. In reaction to the many responses that I received I belive I can enlighen some others with the information I've found. I like many of the people who responded I figured that I could just make a simple modification to one of the existing numeric pager programs that are in the Interact CSL. I was rather suprised when I did a little reading to find that the alpha paging sequence is totally different from anything a numeric pager uses. Numeric paging is completely handled by using touch tones that are generated by a modem attached to the 3000. Alpha pagers, on the other hand, actually require you to make a modem connection to your paging company's "pager central". Pager central is just a computer that takes paging requests, and does the actual paging. Interaction with pager central isn't simply a serial terminal connection, that would be too easy ;-), it's done using a protocol called IXO or TAP. These are two names for the same thing. The paging sequece requires the use of ACK's, NAK's, and a couple of other ASCII characters, as well as calculation and transmission of a checksum for message validation. All in all, it doesn't look to horribly difficult to do, just a real pain. My plan was to find someone else who had already written this program to avoid re-inventing the wheel... Once again, thanks to all who responded... Ray Stevens
