@abdallah-ali-abdallah @pkarashchenko reading it again: "NSH will not print
'\r\n' to devices except /dev/consol. that causes the consol to read shofted
and miss aligned lines"...
I think this is expected because you could use serial devices with NSH that
are not suppose to need "\r\n". Remember: Unix never needed "\r\n" because "\n"
always mean "move to new line" (at the begin of a new line). I think "\n"
meaning move the new line at current column position is something created with
DOS (or CP/M ?). It exist on NuttX because some serial console terminal expect
the DOS/Windows behavior.
@abdallah-ali-abdallah with your modification everything someone send a "\n"
char in the serial it will become a "\r\n" and could prevent some devices to
work. We need to figure-out why CONFIG_CDCACM_CONSOLE is not working...
I found a useful information at apps/nshlib/Kconfig
```
Normally, the serial console device is a UART and RS-232
interface. However, if USBDEV is defined, then a USB
serial device may, instead, be used if the one of
the following are defined:
PL2303 and PL2303_CONSOLE - Set up the Prolifics PL2303
emulation as a console device at /dev/console.
CDCACM and CDCACM_CONSOLE - Set up the CDC/ACM serial
device as a console device at dev/console.
NSH_USBCONSOLE and NSH_USBCONDEV - Sets up some other USB
serial device as the NSH console (not necessarily
dev/console).
```
No idea why CONFIG_NSH_USBCONSOLE couldn't become a /dev/console there
should be some reason why Greg decided to do this way.
