Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Loopback = 0

A bidirectional loopback channel - echos all characters back

§

HelloWorld = 1

An output-only channel for sending periodic sign of life messages

§

PseudoKeyboard = 2

An input-only channel to act as a keyboard for a GUI application such as a forth console, when there is no hardware keyboard available.

Unlike the ForthShell ports, which serve as ssh/telnet like bidirectional items, PseudoKeyboard is only used to receive the input, as the output is shown on a graphical terminal

§

BinaryTracing = 3

A bidirectional for binary encoded tracing messages

§

ForthShell0 = 10

A bidirectional interactive forth shell (1/4)

§

ForthShell1 = 11

A bidirectional interactive forth shell (2/4)

§

ForthShell2 = 12

A bidirectional interactive forth shell (3/4)

§

ForthShell3 = 13

A bidirectional interactive forth shell (4/4)
