4.2 Link Mode Applications
4.2.1 TCP Server Application: Enable Virtual COM
SW550X 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 SW550X’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. Fig. 4.
11. shows SW550X in TCP Server mode with Virtual COM enabled.
