J-Link RTT Client
The J-Link RTT Client is part of the J-Link Software Pack for Windows, Linux and macOS and can be used for simple RTT use cases.
It acts as a TELNET client which connects to the RTT TELNET channel, but automatically tries to reconnect to a J-Link connection when a debug session is closed.

Restricitons
- The J-Link RTT Client does not open a debug connection to the device via J-Link. As an active debug connection is required for RTT to work, the RTT Client can only be used in combination with a J-Link tool that establishes an active debug connection (e.g. J-Link Commander or J-Link GDB Server).
- J-Link RTT Client only supports communication via RTT up & down channel 0
