Samsung E1200 AT commands not working ?!?

Hello,

I am trying to talk to a Samsung GT-E1200i using AT commands (pins 2, 11, 12 on the 20 pin connector).

When I power up the phone, it sends me:

AST_POWERON
OK
BOOTING COMPLETED

During this time (a few seconds), I can send AT commands and the phone responds (AT --> OK, initiate a call, hang up), but after "BOOTING COMPLETED", it stops responding to my commands.

How can I get around this problem?

Also, can anybody tell me which AT commands the Samsung E1200 accepts?
I got the service manual, but it doesn't say anything about AT commands.

Many thanks!

I found out!

In case anyone else has the same problem: You have to ground pin 15 (Adaptor Connect Sense) and the phone will keep listening to AT commands.

Also (I saw this question mentioned elsewhere), there IS a way to switch off or restart the phone through AT commands:
AT+CFUN=1,1 restarts the phone
AT+CFUN=1,0 shuts off the phone

Cheers
