Fax Technology for Embedded Systems

Data communication options for embedded system designers are expanding at exponential rates. One low cost option for transferring information is the use of off-the-shelf fax modem technology. Small, reliable, and economical (less than $100.00) single part faxmodem/DAA packages are available from several sources and can be called upon to send text and graphics to the most ubiquitous printing device in the world – the Group 3 fax. With some accommodation, the same technology can be used to send half-duplex data at 9.6 and 14.4 kbps from embedded systems.
