The 'terminal' you've typed "AT" into is the bash terminal or
which sends commands to the linux kernel.
The 'terminal' Michael is referering to is program sending commands
directly to the modem. The windows equivalent would be Hyperterminal.
Within Linux you could use minicom but many modem controller programs
have a terminal available for sending these 'at' type command directly
to the mode.
I've generally used kppp in the past but obviously there is a range
off programs available.
If this all seems a bit too complicated, there is a fixit day this
coming Saturday. It sounds like you might have some suitable hardware
this time around.

When I try using the command "AT" in root using the terminal program it
responds "Garbled time"
