No Idea, but I've had a number of times where it was issues in source code, rather than other issues that caused problems like this.. For Example.. The Default Printers.pas caused me problems on many operatings systems and printers, but the dxPRinters.pas rewrite works well on everything..
So.. possibly its the delphi interface calls to the vista serial?? wishy washy I know :) On Mon, Sep 20, 2010 at 3:31 PM, Rohit Gupta <ro...@cfl.co.nz> wrote: > I have an eftpos terminal driver written in delphi 2007. > > On XP, it works fine with standard ports and USB-Serial converter. > But on Vista and Win7, it works fine only with the onboard ports.
