You may find that some of these codes are used for programming the scanner itself. Most use "special" barcodes to set up the baud rate, disable/enable symbologies, adding cr+lf to the end, including checksums, etc. Message: 5 Date: Sat, 30 Jan 2010 17:49:54 -0500 From: Adrian Crenshaw <irongeek at irongeek.com> Subject: [Pauldotcom] Barcode and Ctrl+Alt+Del To: PaulDotCom Security Weekly Mailing List <pauldotcom at mail.pauldotcom.com> Message-ID: <edd2c9bd1001301449k240a2910h2f2eb3cb88bcd3bb at mail.gmail.com> Content-Type: text/plain; charset="iso-8859-1" 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: http://www.irongeek.com/i.php?page=security/barcode-ascii 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?
