Figure 20: Step by step replacement of serial transmission devices and (temporary)
preservation of the previous remote control configuration
In addition to the use for remote control protocols there are many more application options
feasible for a serial tunnel e.g. the access to a remote serial management interface or the
transport of more or less any (slow) digital signals ( Chapter 2.21.2, "Serial Protocols and
Sampling Operation").
