does not detect a dial tone after a specified period, it aborts the

You can change this interval using the Dial Wait option.

Instructs the modem to return to command state after dialing,
without breaking the connection. The modem can dial but cannot
train, and no call progress messages are received. This modifier is
used when calling an electronic service that permits the user to
transmit numbers using tones, once a connection is established.
