Finally, if we are planning to use MS Visual Basic as
development tool for building applications we should
use the MSComm serial communications control
which allows direct control access to the standard or
virtual serial port in a PC, which of course has to be
initialized before being used, in this case also a timer
has to be used to continually pool the serial port in
order to receive data from the EVOLUTION Printer. (a
full example of it you can find in the folder:\Printer
Communications\EVCOMMTESTRELEASE\Setup.ex
e).
If, we are planning to use MS Visual C++ or MS
Visual C#, the Serial Port class included in Microsoft’s
.NET Framework is the best tool to be used (a full
example of it you can find in the folder: \Printer
Communications\EVComunications\WindowsApplicati
on14.exe).
There
is
also,
another
application
to
test
comunications between a PC and the EV Printer,
which is located in the folder:
\Printer
Communications\Physical
Connection
Test\EV_TEST.exe).
