Hi,

I am designing user interface using c#. I have connected my hardware kit to PC via usb communication and i am sending some commands from user interface(PC) to get data from hardware.
I am successfully sending commands and receiving response from hardware.

I am sending the command like this

C#

SendCommand("TEMP");

I am trying to send "Esc" button command from user interface. I mean i want to send like this

C#

SendCommand("27");

but not working. I think ESC (character 27) button.

Can anyone suggest me how to send that?

Assuming that SendCommand is your own method, and it only accepts a string:

C#

SendCommand("\x1b");

Should send a single escape character.
