Sun Remote System Control (RSC) User's Guide

Troubleshooting Modem Problems

You can log in to the host as root and use the command rscadm modem_setup to debug modem problems. Then you can issue AT commands to the modem and attempt to dial the paging terminal of your paging service. When you connect successfully to a paging terminal that uses the TAP protocol, you should receive the ID= prompt, indicating the start of a successful TAP connection.

If you cannot log in successfully using AT commands, check modem hardware configuration such as DIP switches, and RSC serial port settings.

Instead of using the rscadm command, you can connect the modem to one of the server's serial ports and use a UNIX utility such as tip to connect to the TAP paging terminal. This allows you to check the modem independent of RSC. If you can connect successfully using this method, you know you are using the correct paging terminal number. See the man pages for tip and stty for UNIX-level troubleshooting.

To check pager alerts, use the command rscadm send_event -c message. This sends an alert message to pagers specified by RSC configuration.
