Virtual Wedge<br />

A Reader Services feature that lets the reader decode bar codes, making the<br />

reader functionally equivalent to a wedge reader connected to a PC.<br />

volatile<br />

Refers to memory that is not saved when power is lost or turned off.<br />

warm boot<br />

One of two ways to boot the reader; compare to cold boot. A warm boot<br />

performs the power-on self test (POST) to ensure that the hardware and<br />

peripherals are operational, runs CONFIG.SYS and AUTOEXEC.BAT, and<br />

displays the DOS prompt. The contents of both conventional memory and the<br />

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

execute startup files, such as AUTOEXEC.BAT, that have changed. You may<br />

also warm boot to start Interlnk.<br />

wedge reader<br />

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

enters the data into the PC as if it were typed at the keyboard.<br />

XON/XOFF<br />

A type of software flow control for communications between digital devices. It<br />

stops the host from sending data when the device buffer fills up (XOFF) and<br />

starts it again when the buffer empties (XON).
