Hello there,
Thank you for your reply.
The Parameter ID is 111, so the SMS command will be as follows:
With login and password : <login><space><password><space>setparam 111:1
Without login and password : <space><space>setparam 111:1
If you are sending via GPRS then you may skip the login, password, and <space>.
Please try this and let me know if it helps.
Kind regards.
