Operating modes
The Mobile Data Service function may operate in three modes:
Command mode
The Mobile Data Service responds to AT commands. No remote
communication occurs.
Online command mode
A data call is taking place and an escape sequence has been initiated, after
which the Mobile Data Service will respond to AT commands during the call.
Online data mode
Once the Mobile Data Service is connected up, anything arriving from the PC
is interpreted as data and sent to the remote end and vice versa.
Basic AT commands
Note: AT commands may be entered in either upper or lower case (not mixed).
