Hi,

AT commands for TRB142 could be found here and could be used the same way as you used TC35i. You could even automate the script to fetch the output of AT+CMGR command and then delete it with AT+CMGD once the output is changed (new message received).

As for remote connection, you can set-up TRB142 to work in overIP or console mode:
