Get Touch Tone Configuration with Digi AcclePort

[kent]

I have a server with an 8 port Digi Accleport modem card in it. I am using 3 modems for dial out with PageGate which works fine. I am attempting to use 1 modem port (The other four are unconnected) for dial in to the Get Touch Tone piece. I have configured the modem with the following default string:
AT&FQ0V1X4S0=1+FCLASS=8 which seems to put in in voicemode. If I use the other string, AT&F0Q0V1X4S0=0#CLS=8 it answers in FAX mode. However if I use AT+VTS={#,5},{#,5},{#,5} to answer, it gets an error as this modem doesn't understand VTS commands. Using AT#CLS=8A as the answer string will work but gives me 0Byte .TTM files.

Using hyperterminal for troubleshooting, when I dial instead of RING it has an arrow pointing right followed by an R. If I answer, I can then type in touch tones. If I press 4, instead of the number showing up I get right arrow / right arrow 4 right arrow ~. I believe this is why Get Touch Tone is creating 0byte files. I was told by Digi tech support that this modem does recognize DTMF tones. Is this normal? Is there a different init string I can use to make this work?

I think you are on the right track, using Hyperterminal to try to test the settings. However, from what you are receiving, it looks like you may have a communications setting mismatch.

In hyperterminal, make sure the parity is set to none, and the databits are set to 8. Then try each of the following baud rates, and see if you can get a 'RING' out of it:

300, 1200, 2400, 9600, 19200

Please post back with your results.

Thanks for the fast response but that didn't work either. If I leave the +FCLASS=8 off then it will say RING but will answer in data mode and of course not accept touch tones. It does the same thing if use #CLS=8.

Even with the R, it will answer but if I press 4, instead of a "4" being received, I get the 4 and an additional 5bytes which is what I believe is confusing Get Touch Tone.

After some digging, I have found out that the odd character is HEX 10 or the <DLE> character.

For a ring in voice mode I get <DLE>R and Get Touch Tone will answer. I assume this is normal.

When pressing touchtones I get <DLE>/<DLE>4<DLE>~ when the 4 is pressed.

I guess my question now is, Is this what Get Touch Tone is expecting? If so then why am I getting 0byte .TTM files?

When the modem is in voice mode, when you hit a '4', that is all that should be received from the modem. I'm sure all the extra control characters are what is confusing the Touch Tone Interface. You may have to go back to Digi and ask them why you are getting all those characters when you simply hit a 4.
