For years, the hand held community has enjoyed error free or near-error free data communications. In the late 70's, the hand held industry used the then standard Bell 202 communication protocol which used Audio Frequency Shift Keying and was limited to 1200 bits per second to transmit their data from a small (by standards in those days) device. The hand held was held up to a phone and orders were magically sent to a host computer. Confirmation of a successful transmission was given either through a tone or voice message.
Most people didn't think about was what was between their phone and the host that was receiving the information. If any thought was given it might have focused on the overhead wires or the wall box where the phone connected. The concern was on the job to be done, send the order in and get to the next client. In most cases, typically 80-90% of the time, the order was placed and life went on.
The industry standard was set by the Telxon 710. A handheld device that boasted a bar code reader, MSDOS as the operating system, a 4 line by 16 character LCD display, and built in acoustic coupler for data transmission. The 710 fit into applications for order sales entry, inventory control, cycle counting, DEX/UCS, and other applications. As the early entry into the market, and a product that generated cost saving and greater efficiency, the 710 flourished and Telxon dominated. The product became an important part of a company's operation so much so that thousands of these units are still in use today.
