Virtual Wedge

A Reader Services feature that lets the reader decode bar codes, making the

reader functionally equivalent to a wedge reader connected to a PC.

Refers to memory that is not saved when power is lost or turned off.

One of two ways to boot the reader; compare to cold boot. A warm boot

performs the power-on self test (POST) to ensure that the hardware and

peripherals are operational, runs CONFIG.SYS and AUTOEXEC.BAT, and

displays the DOS prompt. The contents of both conventional memory and the

physical RAM drive (drive E) remain intact. You may warm boot the reader to

execute startup files, such as AUTOEXEC.BAT, that have changed. You may

also warm boot to start Interlnk.

wedge reader

A bar code reader that connects to a PC. The wedge lets you scan bar code and

enters the data into the PC as if it were typed at the keyboard.

A type of software flow control for communications between digital devices. It

stops the host from sending data when the device buffer fills up (XOFF) and

starts it again when the buffer empties (XON).
