I have problem with call auto answer in modem Huawei E303.
On modems E173 auto call anwer is working fine. But on Huawei E303 it's not working.
Steps that i do: Open kermit:
set line /dev/ttyUSB0 set carrier-watch off c
then i type AT command for answer on first ring:
and when i'm calling on that modem nothing happens. So question is is there something that can be done to make it auto answer or it's a hardware restriction ? i know that on E303 voice is enabled, and i can make call with it by typing ATDT XX_MY_NUMBER;
EDIT: So when i'm calling on that modem i dont see anything in output but if i type in console force answer call at command:
that modem answers the call. So call answering is enabled, but why still ATS0=1 isn't working ?
EDIT2 So I made some debugging with kermit application and ran command: SHOW COMMUNICATIONS
E303 modem returned output: ( modem that does not auto answers on call)
Carrier Detect (CD): Off Dataset Ready (DSR): On Clear To Send (CTS): On Ring Indicator (RI): Off Data Terminal Ready (DTR): On Request To Send (RTS): On
And my E173 modem that is auto answering calls:
Carrier Detect (CD): On Dataset Ready (DSR): On Clear To Send (CTS): On Ring Indicator (RI): Off Data Terminal Ready (DTR): On Request To Send (RTS): On
Other commands like "SHOW MODEM", and "SHOW DIAL" returns same equal output, so only difference is with Carrier Detect (CD): On / Off
So can it be the problem why E303 modem does not make auto call answering if at command ATS0=1 was given ?
