I can't use Ctrl+Z to quit the SMS message.

TO: All GPRS SMS USERS

The voice side of the GPRs works as I can call it and have it call other phones too. However, the SMS side does not work. The SIM card works. The problem is why does the control+Z escape code fail to allow you to leave the SMS message? I have a copy of the SIM900 PDF too. Because I’m a first time user, I can’t copy over the code I used to display the problem I’m having with the GPRS version 1 device. Please Advise.

You could directly send ‘26’ to SIM900 since the ASCII code of the ctrl+z is 26
