pause is desired, more than one comma may be entered
,
consecutively, with each one causing a two second pause. You also have the option of changing
the length of the pause of the comma, from two seconds to any other value from 0 up to 255 seconds. This is
accomplished by accessing S-Register S8, which we explain in Appendix E.
Each comma used in a dialing command does count as one of the forty allowed characters.
Returning to
A semicolon (

), when entered as the last character of a dialing

command, will cause the command modem to return to the

Command mode immediately after executing the command,

instead of waiting for a carrier signal and going on line.
Command
Execution
For example, entering
ATDT5551212;
would simply tone-dial the number, and do nothing
afterwards except go back into
;
Command mode. This can be useful in dialing applications where command
modem data transfer is not desired, such as voice communications.
Escape
It is possible to cause the command modem to enter the com-

mand mode after the command modem has gone on-line

without disconnecting the call. This is accomplished by entering

an Escape code. The default Escape code is three plus

signs (+++). You need not hit Return.The Escape code character
Still On-Line
may be changed by accessing S-Register S2 which is explained in Appendix E.
+++
There is a safety factor built into the command modem, that requires about one second of silent
time before and after the Escape code
+++
is entered, to prevent accidental escapes into the Command mode. The
command modem will not release the telephone line until it receives an ATH or ATZ command, or it detects loss of
carrier.
