Writing Non-ASCII keys in Serial Port

I am trying to send SMS using Matlab through a Nokia phone. I am using AT commands, and one of the commands uses ctrl+z. How can I do this in the M-file?
Thank you.

The value for CTRL-Z (^Z), is 26 (decimal value). So you could just try using FWRITE to send that value, in addition to all the other commands. On a side note, the value for CTRL-A (^A) is 01 and other key combinations from CTRL-B through CTRL-Y are the number in between i.e. CTRL-B (2), CTRL-C(3) etc.
