EHS6T Lan - Modem TCP port 1234 issue | Thales IoT Developer Community

I'm having occasional issues when connecting to a device through telnet on port 1234.
Normally the device is working ok, but after a while the device stops responding to commands correctly and only replies with the character 'A'.
Here's a copy of the comms log:
02/13/17 08:22:46 > ATZ
02/13/17 08:22:47 < ÿû<ETX>ÿû<SOH>ÿþ<SOH>ÿý<NUL>A
02/13/17 08:22:48 > ATE0
02/13/17 08:22:49 < A
02/13/17 08:22:49 > AT+CMGF=1;+CSCS="GSM"
02/13/17 08:22:50 < A
Is there anything I can check to see what's causing the issue?
I've already disabled the SMSTOOLS application as this was intercepting all inbound SMS messages so there shouldn't be anything else talking to the device.
Also, I've modified the ser2netehsfw-0.01.conf file to enable a 30 second timeout on the telnet port 1234.
