Hyperterminal problem

Hi,
I am trying to send a text message using hyperterminal and AT commands
Ex:
at
OK
at+cmgf=1
OK
at+cmgs="2107791679" (also tried at+cmgw)
> hello

When I enter "ctrl z" I get a little arrow after hello
and hyperterminal just hangs there. It doesn't respond or send the message. I have been successful using the other AT commands, as well as, dialing out using at commands.
Is there anything I should change to actually send the message? How long does it take for hyperterminal to send the message?

I'm using:
Bits per second: 9600
data bits: 8
parity: none
stop bits: 1
flow control: hardware (i've also tried none)

I'd appreciate any help. Thanks!

Well.. stop using it, there's tons of better tool than HyperTerm 'round...

Realterm is one of those 1,7004,876 free one. MicroCode Studio's Serial communicator is another one.. no feature... but easy to use.

As it's a PIC based forum, we expect you shopw us your schematic and code... unless it's like fishing in the dark with both eye close...

I've managed to send messages from hyperterminal using a Nokia phone. You might need to add

AT+CSCA = "XXXXXX"

where XXXXXX is the message centre number. So you should have

AT+CMGF=1
AT+CSCA = "XXXXXX"
AT+CMGS = "phone number"
hello

Hope that helps,

Stuart
