"ATDT" is a Hayes modem standard which most dialup modems recognize.
Your cell phone, however, is NOT a Hayes modem and it appears that it's
not Hayes compatible either. I'm sure your cell phone came with some
sort of instructions. Time to read an follow them!

then don't change anything on the host end, it works with a land line or
rs232 cable, at your cell phone/hyper term/end you will have to change the
hyperterm settings to set the max baud rate/vt100 emulation/parity stop
bits/etc

Is it possible that Verizon has disabled CSD ("dial up") functionality on
that phone?
For starters, no digital cellular phone reallyhas a "modem" in the
traditional sense. The phone sends and receives data packets to/from
your wireless carrier, who makes the actual "modem" connection to the
outside world for you. This is called CSD (Circuit Switched Data.) For
it to work, your device has to support it, and the carrier has to accept
CSD connections. Verizon still accepts them, AFAIK, since I use it on my
PagePlus account (a prepaid reseller of Verizon service.)
Since CSD is such an old data standard- it's slow (14.4k max), and
bandwidth wasting (a CSD call hogs the space of a phone call on the
network whether you're actively transmitting data or not, while newer
packet data transfer methods consume no network resourses when idle)
Verizon had disabled it in most phones they've sold in the last several
years.

Thanks for the info, Todd. This could be why I cannot dial out. Time to call
Verizon.
