Windows Standard Serial Communication Library for Visual FoxPro
The Marshallsoft serial communications component library for Visual FoxPro
(WSC4FP) is a serial port library based
on the Windows serial comm API. WSC4FP uses the core Windows API to communicate with any device connected
to a serial port from within a Visual FoxPro application.
A simple interface allows accessing data from a serial port using RS232 or multi-drop RS422 / RS485 serial ports. WSC4FP also supports virtual ports such as those created by Bluetooth and USB/serial converters. WSC4FP provides the capability to quickly write Visual FoxPro applications to control serial devices such as barcode scanners, modems, lab instruments, medical devices, USB serial devices, scales, GPS navigation, etc.
The component library includes 46 functions plus serial line status & control, modem control,
ASCII/XMODEM/YMODEM protocols, and a good selection of Visual FoxPro example
programs. The library can be used with any 32-bit version of Visual FoxPro.
