Looking Beyond Voice Modems in SCADA Systems

Though the days of wedging your phone receiver into a foam cradle are long gone, the name still conjures up the sounds of chirps, bleeps, and bongs they make as they translate analog information into digital. As high-speed networks became our preferred method of web surfing, the use of this technology has steeply declined.
