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!
