TC35i terminal - Help needed to get number keyed in during call

[Dave]

You probably haven't gotten an answer because we don't have a TC35i terminal... Whatever that is.... Why not find the manual for it? I'm sure the info is in there somewhere....

Thanks for the reply Dave. I tried a lot to search the internet, find answer in the manual but no luck (Or may be my novice approach is not letting me see it)
I don't know if my questions depends on the model of the modem (I may be totally wrong). I choose this model as Araati made one SMS switch based on this modem, So I thought of starting it with this modem only as it will be easy to get help when needed. The datasheet of the At commands of this modem is: http://www.xmyn.com/jiuzhan/upfile/200711148574975767.pdf

Hope to get some constructive help soon.
