Trying to connect to FlexiBMS Lite 12S 1.0, I’m not able to issue any commands
b264@computer:~$ cu -l /dev/ttyACM0 -s 115200
Connected.
Invalid command, type "$?" for command list
Invalid command, type "$?" for command list
Invalid command, type "$?" for command list
Invalid command, type "$?" for command list
Anytime I press any key, it immediately responds with Invalid command, type "$?" for command list without waiting for me to finish typing or even press enter.
Does anyone know how to connect to this?
Same thing happens using other connections:
Any keypress immediately responds with error. Any key on the keyboard. (except, it seems, Ctrl+Shift+J)
This is using 115200 baud, 8 data bits, 1 stop bit, no parity, XON/XOFF flow control
No combination of newline settings change anything.
