This class// tries to supply an easy to use interface to deal with serial// devices.//// The class is actually pretty ease to use. You only need to open// the COM- port, where you need to specify the basic serial// communication parameters. You can also choose to setup handshaking// and read timeout behaviour.//// The following serial classes are available: //// CSerial - Serial communication support.// CSerial. Ex - Serial communication with listener thread for events// CSerial. Sync - Serial communication with synchronized event handler// CSerial. Wnd - Asynchronous serial support, which uses the Win. CSerial. MFC - Preferred class to use in MFC- based GUI windows.// //// Pros: // - -- -- // - Easy to use (hides a lot of nasty Win.

There are three forms of// handshaking: //// 1) No handshaking, so data is always send even if the receiver// cannot handle the data anymore. This can lead to data loss,// when the sender is able to transmit data faster then the// receiver can handle.// 2) Hardware handshaking, where the RTS/CTS lines are used to// indicate if data can be sent. This mode requires that both// ports and the cable support hardware handshaking. Hardware// handshaking is the most reliable and efficient form of// handshaking available, but is hardware dependant.// 3) Software handshaking, where the XON/XOFF characters are used// to throttle the data. A major drawback of this method is that// these characters cannot be used for data anymore. LONG Setup. Handshaking (EHandshake e. Handshake); // Read operations can be blocking or non- blocking. You can use// this method to setup wether to use blocking or non- blocking// reads. Non- blocking reads is the default, which is required// for most applications.//// 1) Blocking reads, which will cause the 'Read' method to block// until the requested number of bytes have been read. This is// useful if you know how many data you will receive.// 2) Non- blocking reads, which will read as many bytes into your// buffer and returns almost immediately. This is often the// preferred setting. LONG Setup. Read. Timeouts (ERead. Timeout e. Read. Timeout); // Obtain communication settingsvirtual EBaudrate Get. Baudrate (void); virtual EData. Bits Get.
