is there any way to represent using barcodes the Ctrl key?

Hello, I was wondering if I could print using a barcode font a key like control. I have some old computers here at work dedicated to allow people to sign in at the beggining of the day and sign out at the end. The fact is that the keyboards attached are a problem... people press the windows key continuously... X| Those computers have old screens that I've configured in order to auto shut down after a few minutes without activity (in order to make their lives longer) but of course I need to press a key like control in order to make that that screen return to life. NOTE: I don't need the key [control], I need something that won't affect the sign in/out application in anyway as the key [control] does... it resurrects my screens and doesn't write down anything into the application. A) Does anybody here know if I can print that key in some way as a barcode? B) Could anybody imagine any other way to do it without keyboard and without mouse? only with a barcode reader... Thank you in advance...

Code128 is capable of rendering ASCII control characters. I would recommend one such as BEL (Ctrl+g, 0x8, beeps), BS (Ctrl+h,causes backspace) or the like. These characters are available only in character set A. So your barcode would have to begin with code 103, [START A] to select this character set. Like this: STARTA: 103 BEL: 71 CHECKSUM: [calculated according to checksum] STOP The full spec, in simple terms, can be found here: http://www.barcodeisland.com/code128.phtml[^]
