5.2 Link Mode Applications
5.2.1 TCP Server Application: Enable Virtual COM
SW550xC 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
SW550xC ’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 5.11. shows SW550xC in TCP Server mode with Virtual COM
enabled.
