how to send <ctrl-z> to hyperterminal

hi!
i am working on a project where i need to send SMS through GSM phone.

so, basically, in hyper terminal i can type command and press <CTRl+Z> which marks the end of command and press enter to send the message.

how i can send <CTRL-Z> through class streamwriter? anyone any guess?

basically, its ASCII equivalent is "1A".

well, as always, long live C.

anykind of Ascii symbol can be send to any place, anywhere using the format

\x[ASCIICODE]

so, in my case it came as
\x1A
