mobile reply to AT Commands

Posted by Lennart
Hi all

Trying to communicate with T68i using AT commands.
Using Bray's Terminal (similar to HyperTerminal) on PC side.
Any sent AT Commands from PC are echoed back to PC, but never get the expected "OK".
Instead T68 send "ERROR" appx 20 sec after last AT Command is sent from PC.
Have tested two T68i with same result.
Baudrate = 9600. Tested with other standard baudrates too in desperation.
No luck...
No parity and 1 stopbit is used.
What am I missing?

Problem solved.
The string sent to phone need to end with CR.
