Includes 52 functions plus modem control, serial comm API. WSC4D uses the core Windows API to communicate with any device connectedto a serial port from within a Delphi application.A simple interface allows accessing data from a serial port using RS232 or multi-drop RS422 / RS485 serial ports.
If the Device is connected to a 'Virtual' serial port. USB,PCI or PCMCIA card, then The connection is un stable. And that is why I need a new component. I have a current problem with a 'GPRS VodaPhone connect' PCMCIA Card. Then try to find the source of your problems first. ZylSerialPort is a Delphi & CBuilder thread based serial port component. Use ZylSerialPort component to easily communicate with external devices on serial port connection, such as modems, bar code readers, GSM modules and others. It works in synchronous and asynchronous mode.
WSC also supports virtual ports such as those created by Bluetooth and USB/serial converters.
