AT^SETPORT?
- Display current configuration
AT^GETPORTMODE
- Display currently active mode
AT^SETPORT="A1,A2;1,2,3,7,A1,A2"
- Set default configuration
AT^SETPORT="A1,A2;1,2,3,7"
- Disable CD+SD after modeswitch
AT^SETPORT="A1,A2;2,7"
- Disable CD+SD+modem after modeswitch, keep PCUI and Win7 NDIS mode
AT^SETPORT="A1;2,7"
- CD only, after modeswitch PCUI + NDIS
AT^SETPORT="A1,A2;1,2,3,7,A1,A2,4,5,6,A,B,D,E"
- CD/SD, after modeswitch enable all features (doesn't really do anything different compared to default)
If you try playing with these it's probably best to not ever drop "2" from list of features as that will likely prevent you from reverting changes with AT-commands.
