>Is there abnything provided with VFP 7.0 to read inputs from a serial port, or must an Activex control be purchased to achieve this functionnality?
The MSCOMM32.OCX file provides an ActiveX control (MSCOMMLib.MSComm), the Microsoft Communications Control, version 6.0 which will handle low-level COM port I/O. There are lots of examples in the FAQ and Downloads sections.
