CHAPTER 4: OPERATION AND CONFIGURATION
7400B Data Module
User’s Guide
Page 4-7
The following is an example:
atd74768
[ Enter ]
In the example, the command will cause the data module to go off hook,
dial the number, and then wait the period of time specified in S-register
S7 for the call to be completed.
If the call is not completed, the data module will disconnect and send
the result code NO CARRIER to your display screen. When a call is
successfully completed, the data module will send the result code
CONNECT nnnn to your screen, where nnnn represents the speed of
the 7400B Data Module, (for example, 1200).
REPEATING A COMMAND As mentioned earlier, the command buffer contains the last completed
command line. If you wish to repeat the previous command line without
retyping it, type A/ without the AT command prefix and without
pressing
[ Enter ].
This command is most useful when you have typed a command line to
have the 7400B Data Module dial a number, and the data module returns
the result code BUSY. Use the A/ command to redial the number as
often as you wish.
STORING A TELEPHONE
The 7400B Data Module is capable of storing up to four telephone
NUMBER numbers, each of which can contain up to 25 characters. Numbers
stored in this way remain available indefinitely, even after the data
module has been powered off and then on again.
Table 4-3 describes the command lines used to store a telephone
number, delete a number from storage, and dial a stored number.
Note:
Digits 0 through 9 and all letters “a” through “z” and “A”
through “Z” may be part of the stored “number.” Spaces
and hyphens (-) may be used in the number when typing the
command line. Spaces are not stored and do not add to the
total count of characters in the stored number, but all other
ASCII characters are stored and counted. Any ASCII
character may be used, as long as it is acceptable to the
PBX.
