[comp.dcom.modems] Storing Numbers on a Prometheus 2400G

ceb@csli.Stanford.EDU (Charles Buckley) (07/20/89)

I would like to be able to store telephone numbers in the memory of my
Prometheous 2400G external modem (with a Hayes compatible command set,
using the Sierra chips).  The manual says there are three positions
available, and to store a number you simply use:

AT&Z<your number here>

where your number can consist of the digits, A-D, and various
punctuation symbols (W or ; for pausing, etc.).  The A-D address the
fourth column of the DTMF permutation matrix; its not usually
available by keytouch, but the electronics in most phones can generate
it.

How do you specify whic memory location you are programming?  Simple,
they fill up in sequence, after which successive entries overwrite the
first location.  If you would like to occupy only the first and third,
you must program all 3 and then delete the second using:

AT&ZD2

My problem is, I can only access one memory location.  When I program
in more, it just replaces the previous entry.  Regardles of whether I
enter ATDS1 ATDS2 or ATDS3 (calling up one of the three memory
locations), it dials the last number I have programmed.

Deleting doesn't even work, since syntactically speaking, AT&ZD2
should simply program in D2 as the last number entered.  This is what
it does.

Does anyone know how this feature really works?  I am given to
understand it would work the same on any Sierra-derived modem.

Thanks, ceb
