3.3.9. TCP Server Application: Enable Virtual COM
SE5001A will encapsulate control packets on top of the real data when Virtual COM is enabled. This will allow the
Virtual COM port in the Windows/Linux system to access SE5001A
’s COM ports. The benefit of using Virtual COM is
that rewriting an existing COM program to read IP packets is unnecessary. In other words, it is possible to use an
ordinary serial (COM) program. The conversion/virtualization of IP to COM is all done in the system driver
transparently. Figure 3.26 shows SE5001A in TCP Server mode with Virtual COM enabled.
