Operating modes
The WorldPhone ASD function may operate in three modes:
• Command mode
The WorldPhone ASD 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 WorldPhone ASD will respond to AT
commands during the call.
• Online data mode
Once the WorldPhone ASD is connected up, anything arriving from
the PC is interpreted as data and sent to the remote end and vice
versa.
