WS228 not accept CONTROL-Z


#1

Hi,
i use WS228 version L23 and try send SMS.
AT&F
OK
AT+CREG?
+CREG:0,1
AT+CMGF=1
OK
AT+CSMP?
+CSMP: 17,167,0,0
OK
AT+CMGS="+7…"

Test message — Not accept CTRL-Z but ESC accepted

How to resolve this ?
P.S. Please don’t suggest change to Telit GE865

How are you communicating with the WS228?

Are you sure that whatever you’re using can & does properly send a Ctrl+Z… :question:


#3

I use rsterm terminal
Also for test i connect Telit GL865 and SMS works fine.

What is that :question:

And are you sure that it can & does properly send a Ctrl+Z :question:


#5

Yes - it sent Ctrl-Z, because Telit modem work correctly and Serial sniffer display it in log.

Ah - you mean this: easyvitools.com/rsterm/index.html

Maybe this is what’s confusing the Sierra Wireless (non-Telit) WS228…?

Have you tried using some “neutral” terminal such as hyperterminal or puTTY :question:
