pySerial-Terminal

A more capable(*), modular terminal (* than pySerial's miniterm)

Currently a work in progress.

Misc

There are some layers and indirections. The aim is to be able to implement different I/O devices without re-implementing the escape decoder logic each time.

console

• read keys (return key names)
• output operations using API (query/move cursor, erase parts)
• backends: windows, [posix, GUIs]

terminal

• escape_decoder: decode escape sequences and call methods on emulation object
• providing constants

emulation

• mapping escape_decoder calls to console
• simple version decoding colors and movements, not supporting some of the features
• [aiming for] nearly full VT220 (e.g. no printing support)
