Hi,

Manual says, "a ctrl Z must be added at the end of message
to send the sms".

I put ascii 26 decimal or 0x1A plus cr and lf at the end
of sms but, but the the gsm did not send.

I have searched the forum, and there a back slash before the
0x1A, I have it tried, but did not work too.

But in the text file processing it works fine.

Is there any char need to be added, to activate
the gsm to send the message?

The gsm is Siemen C35.
Thank you in advance.
