5.2.2 TCP Server Application: Enable RFC 2217
The underlying protocol of Virtual COM is based on RFC 2217, the Telnet COM Control Option.
Therefore, it is possible to use RFC 2217 with SW550xC in the TCP Server mode. To do so,
refer to Sec. 5.2.1 to enable Virtual COM, so that SW550xC becomes aware of the commands.
Note that there is no need to configure Virtual COM on the Operating System because Virtual
COM ports would not be used.
5.2.3 TCP Client Application: Enable Virtual COM
It is also possible to run VCOM in TCP Client mode, Figure 5.12. It is usually easier to use
Virtual COM in the Client mode if SW550xC uses dynamic IP (DHCP) because setting a static
IP address in Virt ual COM’s Control Panel in the Operating System is not possible.
Figure 5.12
 Follow Sec. 5.1.2 to configure SW550xC in TCP Client mode properly.
 Click on the dropdown box of the Application option and switch to “Virtual COM” to
enabled Virtual COM application in SW550xC.
 Scroll to the bottom of the page and click on “Save & Apply” button to save the
changes.
