; (semi-colon)
Terminates the dial string, and returns to command state after
processing a dial command.
at dt 9,1 800 624-5123; dp 555-1212; O
The semi-colon returns you to a command state and allows you
to enter more commands.
In the above example, a data call is made, and the semi-colon
returns you to the command mode. A voice call is then made
and the o sends you back to the data connection.
When the dial command specifies a stored number to be dialed,
the semi-colon can be entered after the S=n command. If a semi-
colon is omitted, the voice call is made, but all commands
following the dial command will be ignored.
If the dial command for a voice call is the last command on the
command line, the semi-colon dial modifier may be omitted (the
7400B Plus will still return to the command mode).
