An error buffer is implemented in each terminal to store data on terminal operation errors. To display the buffer contents use either the terminal (an AT command) or an SMS.
SMS:
The SMS displays the last 10 errors starting with the most recent one.
SC ERR PWD=<password> [CLR]
This command includes one optional parameter – CLR. If you add this string after the password in the command SMS, you will receive an SMS showing the current buffer contents and all errors will then be deleted from the terminal memory.
The following reply will come from the terminal after processing:
1:8,10 2:3,10 1:1,0 7:8,10 6:8,7 5:7,40 4:11,848
AT COMMAND:
Error codes are obtained by AT^SCERR? which response is:
^SCERR: {id}> {ID}, {Additional value}
id - Sequence number of the error since the last start-up.
ID - Error identification. See table below.
Additional value - Detailed information
This table describes the meaning of the 2N® SmartCOM PRO reset error codes.
