Good day.
After starting the modem sends to COM <0>. Stops responding to AT commands.

Can't find a solution to this problem.
Hello,
Which port is it ASC0 or USB? How about other ports - is it still possible to communicate? Maybe there's some MIDlet running on the module which takes over the port. Please check AT^SJAM=5, AT^SJAM=4 and AT^SCFG?
Regards,

Hello.
Port ASC0(RS232).
AT ^ SCFG?

Hello,
As I understand it is possible to send a few commands before it stops responding.
Problems with communication could be caused by power saving on serial interfaces - please check AT^SPOW? output and set to 1,0,0 if necessary. With power saving active you should be using hardware flow control. As I see it is configured on the module (\Q3). Please make sure that you have it configured in your terminal and if the lines are connected. Please also check AT+IPR? output - you need to do it on ASC0 interface. However these <0> characters are strange for me. Maybe they are related to your terminal. Or there is some hardware issue. Do you connect the device to PC or some other device? Do you use USB-RS232 converter? These devices may be causing problems sometimes.
Best regards,
Bartłomiej
Thanks.
The problem was SPOW.
AT ^ SPOW?

Changed to 1.0.0. The modem works as I need.
