Good Day,
We are experiencing an issue with smslib.
Scenario
1. Computer dials up on 3G Modem and is connected to internet
2. SMSLIB is initialised
3. 3G connection gets lost
Details
Qualcom Driver 2.0.7.3 Works
Qualcom Driver 2.0.6.9 Works
HP Driver 5.20.2.0 (Disconnects)
Qualcom Driver 2.0.7.2 (Disconnects)
Any ideas as to what could cause this?
