I have a command console modem utility that lets me send commands to a
modem and register the response, plus I have a function 'getavar' that
opens a text file, searches for a marker, then collects to a memory buffer
named 'thestring' ... the string ... immediately following the marker.
I want some minor modification done to the getavar function and I ultimately
want to build my modem program with a link to a new file named mytools.cpp.
