URGENT: Hayes "ATD" command to dial DMTF after voice call

[honggo]

Hi

I'm new to Hayes AT command
I read some of the reference and still have some doubts
to clarify

What i wanted to do is using
1. use Hyper Terminal to dial a certain number
I manage to do it using ATD97600000;
2. I will be prompted to sort of IVR/electronic system
whereby i need to dial DMTF Tone (keypad) to continue. I've tried all sort of combination of ATDT or ATD but to no avail


I will be very grateful if someone could enlight me with some simple code in AT Command syntax

regards,
Honggo

If you want to send digits 1234 in the middle of a voice call, then send "ATDT1234;" to the modem. It works on my Hayes modem.

It's not just "ATD####" it's "ATDT####". You must have another "T" after the "ATD". Hope this helps.
