Appendix A - Bar Code Scanning Escape Characters The four escape characters in the previous table yield a VT220 data stream key press equivalent when followed by another character. The escape characters are: • $ (dollar sign) • % (percent) • + (plus) • / (forward slash) For example: • If a bar code contains the sequence %U somewhere within it, the computer treats this as an Enter keypress and processes the sequence as soon as it is encountered in the scanning buffer. • +B is converted to the lower case b. • %B is converted to an F11 key press. If you want the Encoded Code 39 option but the bar codes to be scanned already contain the $, %, +, or /, character, then each place where these characters occur must be expanded to a special / sequence: • Every bar code where the $ is maintained must be expanded to a /D sequence. • Percent signs % must be expanded to /E. • Forward slashes / must be expanded to the letter /O. • Plus signs + must be expanded to /K. Overriding Auto Tab Scan and Auto Enter Scan (3270) When the computer is in Auto Entr Scan or Auto Tab Scan mode, eight Encoded Code 39 functions override these modes when they are scanned. • Forward Tab and Back Tab • End of Field and Home • Backspace and Insert • Clear and Delete These codes are all of the screen-editing type, where an automatic Enter keypress is not desired. The listed encoded operations never allow an Auto Entr Scan to occur. For example, if Auto Entr Scan was enabled and a $C (forward tab) was scanned, the computer forward tabs to the next field, but does not perform an Enter keypress, even though the Auto Entr Scan feature is enabled. In this case, the encoded forward tab overrides the Auto Entr Scan mode. However, if a +D is scanned, the computer places the letter d at the current cursor location and the Auto Entr Scan mode then executes an Enter keypress. 160 Intermec Terminal Emulator (ITE) User Guide
