I saw a solution is press ESC to cancel operator. Do you know what ASCII number I need to send to port? Maybe 27?

The ASCII escape character 27 <ctrl+[> is an alternative to char 26 <ctrl+z> in the +CMGS command syntax. It aborts the command instead of attempting to send an SMS.

I doubt it would abort the sending, or perform any other function, after <ctrl+z> has already been given.
