F.4 Phone Number Memory Commands
Storing Phone Numbers D...N
A telephone number and command line of up to sixty characters may be stored in the
MMH2834’s number memory. As many as ten of these numbers may be stored. Each number
will be given a name, using the codes N0, N1, N2 up to N9. A phone number is stored by
entering ATD, then the number as it would be dialed, along with any P, T, R, ; or comma
characters, and then entering N followed by the number’s “name,” which would be any number
from 0 through 9, and then hitting RETURN.
For example, the tone-dialed number 1-612-631-3550 would be stored as number N3 by entering
ATDT16126313550N3 and RETURN. The number is not dialed with this store command. After
storing a number, check to see that it has been stored correctly by typing ATL and hitting
RETURN.
When phone numbers are stored, the entire command line is also stored so that you can
effectively create a macro for each number. For example, if you know a particular number needs
to detect busy signals or dial tones, and needs extended result codes, error correction, XON/
XOFF flow control, pacing, and data compression enabled, the command line would be:
ATX4&E1&E5&E13&E15DT16126313550N3. This would store the entire command at location
N3.
Number Linking N...N
You may command the MMH2834 to dial another number automatically if the first number dialed
is bysy. This would be useful in a situation where a computer can be accessed through more
than one phone number. This is called “linking.” To link the number in N1 to the number N2,
simply enter ATN1N2 and hit RETURN. Several numbers can be linked in the same command.
For example, you could link N1 to N2 to N3 to N4 by entering ATN1N2N3N4 and RETURN or you
could link N1 to N2 and back to N1 and then back to N2 by entering ATN1N2N1N2 and
RETURN.
The only limit on the number of numbers that can be linked is the 60 characters allowed in a
command line. Number linking can not be used with blind dialing, since busy signals would not be
detected. You would have to select the Wait-for-Dial tone dialing method using the X Command in
order to use the Number Linking feature.
Listing Numbers Stored in Memory L
Telephone numbers that you have stored in the MMH2834's memory may be listed and displayed
with the L command. It will display all ten stored N numbers in a format like that shown below.
All digits and command letters will be shown. The storage location number (0–9) is shown first,
followed by the complete dialing command and telephone number as originally entered.
Simply enter ATL and hit RETURN to display these numbers on your video screen or printer. An
example of an L command listing is shown below:
0 T14082345678
1 T16125551212;
