Zoom AT commands SB.Net Sun, 30 Aug 1998 13:50:05 -0700

Hi Guys;
 I'm trying to use a Zoom 2925 modem as Phone-Interface-C and am having
trouble getting it work correctly.

In order for ECS to reset or initialize the modem I had to comment out the
following in PHN_C.SET.


|ATZ                                              // reset
?|AT$$H8&W                              // disable HOT-SCAN feature
|ATX4                                           // send ALL responses
//       |AT#CLS=8                        // enter voice mode (for DTMFs,
etc)
//       |AT#VTD=FF,FF,FF         // ena ALL DTMFs, ALL modes
//       |AT#VRA=60                     //  remote phone "answered" if no
ring after 6 secs
//       |AT#VRN=60                     // remote phone "answered" if no
ring after 6 secs
//       |AT#VBT=1                       // .1 sec beeps
?ATS30=60                               // assure recovery if DTE dies (???)
//        |AT#VSP=50                    // silence tmo = 5 secs ???
//        |AT#VLS=4                       // line-input, spkr & line/handset
ena
//        |AT#CID=2                        // enable caller-id


I realize this modem doesn't have Caller-ID but it does have voice mail, so
I was hoping to use it without the
Caller-ID function. Unfortunately, I had to disable the following AT
commands.

AT#CLS=8
AT#VTD=FF,FF,FF
AT#VRA=60
AT#VRN=60
AT#VBT=1
AT#VSP=50
AT#VLS=4
AT+CID=2

I thought all modems with Rockwell chipsets had the same AT commands, or at
the very least, all Zoom modems would share the same commands. A visit to
Zooms web page was not very helpful, as I couldn't find
half of the commands Mark put into PHN_C.SET. Is there a way to find the AT
commands for this modem that
I could insert into PHN_C.SET to make all but the Caller-ID work, or is
there a way to query the modem to find
the commands in the modem's ROM?

Thanks;
 Don
