Using "virtual" Terminals in RTT

For virtual Terminals the target application needs only Up Channel 0. This is especially
important on targets with low RAM.
If nothing is configured, all data is sent to Terminal 0.
The Terminal to output all following via Write, WriteString or printf can be set with SEG-
GER_RTT_SetTerminal().
Output of only one string via a specific Terminal can be done with SEGGER_RTT_Termi-
nalOut().
The sequences sent to change the Terminal are interpreted by RTT Viewer. Other applica-
tions like a Telnet Client will ignore them.

Using Text Control Codes

RTT allows using Text Control Codes (ANSI escape codes) to configure the display of text.
RTT Viewer supports changing the text color and background color and can erase the Ter-
minal. These Control Codes are pre-defined in the RTT application and can easily be used
in the application.
