I know this has been covered in other posts and threads, and I have tried adding loglevel_lac_ci = 8 to the modem section of my conf file (see below), however the CREG command is still sent to my modem, which does not respond.

devices = GSM1
outgoing = /var/spool/sms/outgoing
checked = /var/spool/sms/checked
incoming = /var/spool/sms/incoming
logfile = /var/log/smstools/smsd.log
infofile = /var/run/smstools/smsd.working
pidfile = /var/run/smstools/smsd.pid
outgoing = /var/spool/sms/outgoing
checked = /var/spool/sms/checked
failed = /var/spool/sms/failed
incoming = /var/spool/sms/incoming
sent = /var/spool/sms/sent
stats = /var/log/smstools/smsd_stats
receive_before_send = no
autosplit = 3
loglevel = 7

[GSM1]
loglevel_lac_ci = 8
report_device_details = yes
loglevel = 7
device = /dev/ttyUSB2
incoming = yes
pin = ignore
baudrate = 2400




The error is:

I've spent hours on this and simply cannot work out what I am missing.

How to I prevent CREG from being sent, or have the response ignored?

Try check_network = no

Okay, that worked! Thanks

Now, how about ignoring AT+CIMI?

The modem is a Z-Text PSTN modem, A V.23bis modem which contains a GSM command stack, however it only implements some of the GSM commands.
