STATUS_CTX_MODEM_RESPONSE_TIMEOUT
The modem did not answer the command in time
This status indicates a timeout in the modem command/response path. The server sent a command and waited for a modem response, but no acceptable response arrived within the required interval.
Check the physical and driver-level path: cabling, power, serial/USB adapter state, modem driver, TAPI configuration and whether another process already controls the device.
What to inspect
- Check modem power, cabling and COM/USB device state.
- Review TAPI/RAS logs for command timing and device ownership.
- Do not confuse this with an RDP protocol timeout on TCP port 3389.
