commands: change Y-Modem implementation
The current Y-Modem implementation has some limitations:
- Y-Modem/G protocol is not supported
- Multiple files (aka. batch) transfers are not supported
- Transfer speed over fast lines (USB console) is slow
- Code is not trivial to maintain (personnal opinion)
This implementation tries to address all these points by
introducing loady2 command.
The effects are :
- transfer speed for Y-Modem over USB jumps from 2kBytes/s
to 180kBytes/s
- transfer speed for Y-Modem/G jumps to 200kBytes/s
- multiple file transfers are possible
This command was tested on a USB console and UART 9600bps
serial line :
- NAKs (and retransmissions) were tested for faulty
serial lines
- multiple file transfers were tested
- Y-Modem, Y-Modem/G and X-Modem transfers were tested
