How can modems achieve 56kbps when the theoretical limit it approx 30kbps.Are they using some special software techniques or what kind of modulation are they using.
Hi,
I am wondering if any one has any interesting and working VB form that can send and recieve data via the com port.
A simple program that uses a start/stop command. It may save me some time in testing a project that i am working on.(reading informatio of a PIC through the com port.)
Thanks.
Lin
