Table 8–4 SCM Troubleshooting (Continued)

Symptom

SCM will not answer when modem is called.

After the system is powered up, the COM1 port seems to hang and then starts working after a few seconds.

New escape sequence is forgotten.

Possible Cause

On power-up, SCM defers initializing the modem for 30 seconds to allow the modem to complete its internal diagnostics and initializations.

This delay is normal.

Suggested Solution

Wait 30 seconds after powering up the system and SCM before attempting to dial in.

Wait a few seconds for the COM1 port to start working.

At the SRM prompt, enter the following: P00>> SCM show status

The escape sequence is shown in the output.

Or, reset the system to factory defaults.
