The rs232 is stdout, using printf in ndless programs outputs to there.

Nice compu :)

I really should export Ndless's program launcher to let you call it instead of replicating it in your shell. This would avoid:
- bugs duplication such as the missing clear_cache() in your code which may make the launch crash in some conditions
- breaking your shell if the program format changes, which may happen when new features are included (such as compatibility flags or other programs metadata)

Update :)

- Using on-screen console instead of RS232
- Launched programs can use Nspire I/O to write to (and read from) rshell's console
- Programs that need to be run with rshell have the header "RSH\0" instead of "PRG\0" to prevent errors when launching with the standard loader
- Included program rshell_header.exe to replace "PRG\0" with "RSH\0"
- Launching a program does not require the .tns ending anymore
  (for example you can type "ls" instead of "ls.tns")

My solution isn't very memory-efficient yet, because I didn't get shared variables/functions to work.

Is that a run indicator I see in the corner?

Update:

Made compatible with Nspire I/O 2.0.
+ I have ported argtable2 which allows us to have fancy command-line arguments, and therefore to create powerful console applications :)

Download can be found at http://nspforge.unsads.com/p/rshell/downloader

And a screenshot of what argtable2 can do:
