串行通讯控件

串行通讯控件源代码,适用delphi,pascal源代码,COMM32.PAS is a simple Communications VC for Borland Delphi 2.0 which demonstrates the Win32 Communications functions and the new Delphi 'TThread' class. It is implemented using two threads: one for reading from, and one for writing to a Comm Port. It probably needs to be implemented as a single thread for read/write operations if it is needed for any synchronisation functions (such as file-transfer algorithms). I started to create a 'TAPI' component to use in conjunction with this component (hence the 'OnRequestHangup' property) but as of this version it is incomplete.
