Symbol began to make small computers that could store data scanned to take inventory counts remotely and then upload the information gathered to a host system. This was the rationale for the September 1988 purchase of MSI Data Corporation, a mobile computer company headquartered in southern California, for $120 million.
An ISIS interface can run scanners at or above their rated speed by linking drivers together in a pipe so that data flows from a scanner driver to compression driver, to packaging driver, to a file, viewer, or printer in a continuous stream, usually without the need to buffer more than a small portion of the full image.
A male DE-9 connector on an IBM PC compatible computer (with serial port symbol) used for an RS-232 serial port A female DE-9 connector on an RS-232 cable.. A serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. [1]
Later personal computers (and other devices) started to make use of the standard so that they could connect to existing equipment. For many years, an RS-232-compatible port was a standard feature for serial communications, such as modem connections, on many computers (with the computer acting as the DTE). It remained in widespread use into the ...
The ZEBRA was a binary, two-address machine with a 33-bit word length. Storage was provided by a magnetic drum memory holding 8K words organised as 256 tracks of 32 instructions; accumulators were also implemented as recirculating drum tracks in a manner similar to that used in the Bendix G-15 .

The first scanner to store its images digitally onto a computer was a drum scanner built in 1957 at the National Bureau of Standards (NBS, later NIST) by a team led by Russell A. Kirsch. It used a photomultiplier tube to detect light at a given point and produced an amplified signal that a computer could read and store into memory.
Today, few consumer-grade PC-compatible computers include COM ports, [3] though some of them do still include a COM header on the motherboard. [4] After the RS-232 COM port was removed from most consumer-grade computers, an external USB-to-UART serial adapter cable was used to compensate for the loss. A major supplier of these chips is FTDI.
