User Manual V. 1.1
3.5 TCP Server Application
3.5.1 Enable Virtual COM
SE5002D 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 SE5002D ’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 keep your ordinary serial (COM)
program. The conversion/virtualization of IP to COM is all done in the system driver
transparently. The following figure ( Fig. 3. 27 ), shows SE5002D in TCP Server mode with
Virtual COM enabled.
