HI, just spent 2 hours to thy to find the answer to this.. then I ask on the forum. Thanks

This is a message to be sent.

I would like to know what is the method to type CONTROL Z with my MAC KEYBOARD. Is it \x1a? ou something else?


This is a MAC question! NOT an Arduino question.

No need to tell me that, I knew it. For your info I was learning the Arduino- modem interface commands. Thank you for your very great kindness.
