I am using screen to communicate with arduino over serial port, i start screen like this:
screen /dev/ttyACM0 115200
then I try to send a command but every key I press on the keyboard get sent straight away, how to make it wait until I press Enter key before sending input to arduino?
Here's my serial device /dev/ttyACM0 settings:
$ sudo ssty -F /dev/ttyACM0 -a
speed 115200 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^H; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R;
werase = ^W; lnext = ^V; discard = ^O; min = 100; time = 2;

My .screenrc file is empty.
-icanonindicates canonical (line-based) processing is disabled, so one thing to try would be usingsttyto flip that (thescreendocs I have don't list a direct means to change that). – thrig Nov 10 '16 at 21:13sudo stty -F /dev/ttyACM0 icanonbut nothing changed. – razzak Nov 10 '16 at 21:20ttyACM0?
