I was fortunate to have worked for a small newspaper communications company (Micro-comm, not the modem company) that sold equipment to service such as AP. In the mid 80's AP and others were updating their equipment to more modern equipment. Their wire services use a rather unique set of protocols such and hi and lo speed TTY, versions of Baudot, 7 bit ASCII and other protocols on current loop and normal pots lines. I got to play with news wires and equipment that had been self built (1918 Underwood with a motor and transmission to receive 27.8(?) baud news wire). We built modems (300/1200/2400) that could handle these odd procotols and bit rates and translate to ASCII. We built teletype replacements using OKI data printers. To this day I know the sound of the teletype, EPSON and OKI printers when heard in the background. :-) -- Linux Home Automation Neil Cherry ncherry@linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies KD2ZRQ
