Troubleshooting

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).
