noam came up with this for seeing serial outputs from two usb-connected arduinos
screen /dev/ttyUSB0 #in one terminal
screen /dev/ttyUSB1 #in another
how do I save the output? I tried screen /dev/ttyUSB0 |tee output.txt but don’t see anything written to output.txt
Does screen -L (write a logfile) help? I’ve not got anything handy to test on I’m afraid.
screen has some options for logging. screen is accessing the terminal directly I guess, so not writing to /dev/stdout. anyway man it for how to log. I do not recall.
Remserial or remserial2 which i made.
Connect serial to an telnet port, e.g.
netcat -l 2222 > file.bin
Which is Port 2222 tcp i guess, while udp is unlikely.
Look for remserial2 on github and compile it.
remserial2 has better helpband hex dump view.
Have fun
