UART connection

[Yoast]

Screen works (as well as minicom and picocom).

Which version of picocom works for you ?
Mine, v1.7, gives me "FATAL: failed to add device /dev/ttyUSB0: Invalid baud rate" ...

Code:

[root@mbp_arch ~]# picocom --help
picocom v3.1

Compiled-in options:
 TTY_Q_SZ is 0
 HIGH_BAUD is enabled
 USE_FLOCK is enabled
 LINENOISE is enabled
 HISTFILE is: .picocom_history
 USE_CUSTOM_BAUD is enabled

Most likely the compile options USE_CUSTOM_BAUD and HIGH_BAUD are needed to enable the 1.5M baud rate...
