Use of Cntrl Q

[kwl]

I have an application where I'm controlling a device via the serial port. To get it to exit from one of the menus, I have to send it a "CNTRL Q". In Labview this is the shortcut for quit and i get the dialog box to exit, save, etc.

Could someone tell me what I need to do to configure labview such that I can use the string constant or other means to send the "CNTRL Q" via the serial port.

Thank you

Take a look in your documentation. CTRL Q is not CTRL Q keys but a combination of one or more ASCII codes in range 0-255

According to the ASCII-Table.com hex 11 (decimal 17) is the equivalent of CTRL-Q for terminal programs.

Just create a numeric constant with that value typecast it to string and send it over the comm port.

You could also make a string control\constant and set to "\codes display" or hex display by right cliking on it. Goto labview help and search for strings, backslash codes display
