LXE BCWEDGE 109
E-EQ-MX3RG-J-ARC MX3 Reference Guide
LXE BCWEDGE
This DOS based utility, BCWEDGE.EXE, is installed by LXE.
This Terminate and Stay Resident (TSR) program is used to redirect input from COM1 or COM2
to the BIOS key ring buffer. This DOS based utility enables the use of a barcode scanner on a
COM port, provided power is available on that port. The software interprets data from the scanner
as keyboard data, thus it will work with DOS applications such as EDIT. It will not function on
Microsoft Windows 95 platforms.
When a terminal emulator program is started after the wedge utility has initialized, the keyboard
interrupt used by the wedge utility is trapped and used by the terminal emulator. The keyboard
interrupt needed by the wedge utility is no longer available.
Note: It is the responsibility of the application programmer to make the MX3 beep on errors,
etc., when running the wedge utility.
