Two new types of modems let you combine voice and data
on a single line. Switched devices modulate data over a carrier and then alternate the full modem bandwidth between that signal and a normal voice channel. Simultaneous devices digitize voice and merge it with a data signal and then modulate the synthesized bit stream over a single carrier, in effect sharing the modem's bandwidth between the two sources. Both types typically come with software that supports file transfer during voice phone calls, and many include (or support) whiteboarding packages for sharing and marking up documents while discussing them.
Flexible C++

My approach to software engineering is far more pragmatic than it
is
theoretical--and no language better exemplifies this than C++.
