3.3.10. 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 SE5001A in the TCP Server mode. To do so, refer to section
3.3.9 to enable Virtual
COM, so that SE5001A 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.
3.3.11. TCP Client Application: Enable Virtual COM
It is also possible to run Virtual COM in TCP Client mode (Figure 3.27). It is usually easier to use Virtual COM in the
Client mode if SE5001A uses dynamic IP (DHCP) because setting
a static IP address in Virtual COM’s Control
Panel is not possible.
