Barcode and Ctrl+Alt+Del

[thinkt4nk at gmail.com (Ryan Bales)]

Yeah, I work in POS. Most wedges are supposed to send a CR after a
successful read,  but you should be able to program them to omit the CR.
Keep in mind the fact that most readers are programmed by vendor supplied
barcodes. What type of reader are you using? I have access to symbol
ls2208's and a few Magellan scanner/scale's

As some of you know, Mick and I are F-Ing with barcodes. I've found that
some of the lower 32 ASCII characters are interpreted as special keys by
barcode reading keyboard wedges. I think I'm close to doing a Ctrl+Alt+Del
with Code 128 bar codes. I've got a test sheet up, let me know if your bar
code readers interpret things the same way:

On mine, Code 128 for the lower 32 seems to translate to:

ASCII0[Enter]
ASCII1[Insert][Enter]
ASCII2[Home][Enter]
ASCII3[Page Up][Enter]
ASCII4[Delete][Enter]
ASCII5[End][Enter]
ASCII6[Page Down][Enter]
ASCII7[Left][Enter]
ASCII8[Backspace][Enter]
ASCII9[Tab] [Enter]
ASCII10[Enter][Enter]
ASCII11[Down][Enter]
ASCII12[Right][Enter]
ASCII13[Enter][Enter]
ASCII14[F1][Enter]
ASCII15[F2][Enter]
ASCII16[F3][Enter]
ASCII17[F4][Enter]
ASCII18[F5][Enter]
ASCII19[F6][Enter]
ASCII20[F7][Enter]
ASCII21[F8][Enter]
ASCII22[F9][Enter]
ASCII23[F10][Enter]
ASCII24[F11][Enter]
ASCII25[F12][Enter]
ASCII26[Up][Enter]
ASCII27[Esc][Enter]
ASCII28[Ctrl held][Enter]
ASCII29[Shift][Enter]
ASCII30[Alt held][Enter]
ASCII31[Enter]


I think my reader automatically puts on the ENTER key. I don't have a
printer at home, but later I ant to rey to send
28
30
4
and see what happens. Shmoocon and the barcode contest might be interesting?
