How to make configuration changes to serial port reboot resistant?
Issue
Currently when running "stty -a -F /dev/ttyS0
" the output shows:
speed 115200 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R;
werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 1;

The option which needs to be changed is crtscts
We can disable it manually with "stty -F /dev/ttyS0 -crtscts
" however after reboot the previous situation is present: crtscts
How to make it permanently to "-crtscts
"?
