If your pager service generates repetitive tones when it answers, the HP TopTools
Remote Control modem may interpret the tones as a busy signal and attempt to
re-dial. To prevent this, change the X4 command in the modem initialization
string to X0 (blind dialing).
Can I use HP TopTools Remote Control to page cellular phones using Short
Message Service (SMS)?
SMS (Short Message Service) enhances paging by providing the ability to send
and receive short messages up to 160 characters over cellular phones. If your
cellular phone service supports the TAP protocol, you can use HP TopTools
Remote Control to send SMS notifications. Here’s how it works: HP TopTools
Remote Control sends a notification to the provider using TAP, and the mobile
service provider transmits the message to the cellular phone using SMS.
A test TAP page initiated by my server was never received by my pager.
The following event codes indicate conditions that interfere with successful
paging.
20202: No Connection
Event code 20202 occurs when one of the following conditions is detected:
1. Your terminal is busy and thus was unable to connect.
2. Your modem is not plugged into the phone line.
3. The terminal may be inactive. Paging companies incur occasional
down-time as they make upgrades and repairs to their terminals.
4. You may have selected the wrong number for your Terminal Access
Number. This number should not be the same as your pager number. After
dialing, you should hear standard handshaking protocols begin upon
connection.
5. Your modem is having trouble connecting at 300 or 1200 baud. Baud rate
difficulties can usually be rectified by entering the correct initialization
string for your modem. Modem initialization strings for modems
supported by HP are listed in Appendix B.
20203 TAP: No ID=Prompt
Event code 20203 occurs when the terminal does not allow the HP TopTools
Remote Control card to log on to the terminal system. The most common cause is
that your modem is unable to connect at 300 Baud. To correct, see 20202 above
(condition number 5).
