6.8 Remote Configuration
During a CSD or “TCP transparent” data connection, the INSYS
GPRS 5.1 serial can be switched to remote command mode by en-
tering the escape sequence via the data connection from the re-
mote terminal.
Note: After the 4 escape characters were entered at the local de-
vice (1 second pause before and after the entry, no re-
turn -
<CR>
-), the remote configuration at the remote
terminal is activated. The data connection is main-
tained in the background. The 4 escape characters must
be entered within 1 second.
If this was configured, the configuration password is queried be-
fore the switching to the remote command mode occurs.
Note: See also Chapter
6.1.1
- Password Protection
After the escape sequence is detected, the prompt for entering
the password appears.
If no valid password is entered within 30 seconds (attention:
complete the entry with line end character), the configuration
mode will be exited with the following message
A valid password is acknowledged with
OK
; now the
AT
com-
mands released for remote configuration can be entered.
Terminate configuration
Note: Due to the sometimes long packet run times for TCP
connections, the escape character **** must be sent in
one TCP packet. Otherwise the pauses between the in-
dividual characters get too large and the reception of
the sequence is terminated.
