We are a experienced Delphi programmers from Delphi1 come out on the market.
We had worked using TCommport in a lot of apps (printers, led panels, ...)
We have a TComport source library checked and changed/fixed (because it had some problems/faults originaly).
You can check in our portfolio what kind of complex apps we are able.
But we need know all speces for price valuating.
