It has been developed up on request of Mark Kuhnke (he found my email address in the Delphi EXchange Expert's Area). It is released as FreeWare. You can use it in commercial and non-commercial applications provided that a simple acknowledgement is placed somewhere (help file, about box, readme.xxx, ...). TCommPortDriver features: - supports Delphi 2.0 only (uses Win32 API - COMDRV16.ZIP also available) - is invisible at run time - can handle only first four COM ports (COM1/2/3/4) - supports all standard baud rates from 110 to 115200 - adjustable COM settings (baud rate, byte size, stop bits, parity, handshaking) - supports NONE, XON/XOFF, RTS/CTS, XON/XOFF + RTS/CTS handshakings - send data by calling SendData()/SendString() methods - receive data asyncronously by providing an event to be called when data is available - supports variable sized in/out data buffers ! Full source code included ! Enjoy! ---------------------------------------------------------------------- HOW TO : - Install TCommPortDriver: Warnings: you must install this component before opening the demo ! if you open the demo app before doing this, Delphi will remove the component declarations from the source code and the demo will no longer work ! - To install this component follow the usual steps. 1. Select <Component|Install...> 2. Select <Add...> button from the "Install components" dialog box 3. Select <Browse...> button from the "Add Module" dialog box 4. Select "CommDrv.pas" and then <OK> 5. Select <OK> from the <"Install components" dialog box 6. Delphi will now recompile the components library 7. All done ! You can find the TCommPortDriver component in the component palette ("System" tab) - Now you can open the demo app (ComTest.DPR) and run it.
