Using serial console with a bootdelay of only 1 second is ok, but using usbtty is not. In fact is not possible to stop boot sequence anymore unless bootdelay is increased at least 10-15 seconds needed to run the terminal on the new ttyUSB0 device and to enter the password.
Also I notice that when usbtty is selected as the default console the system doesn't start up until I connect the kermit/minicom to the new ttyUSB0 device.
Hmm, you might want to change
unsigned int len = 0; while(len > 0) { usbtty_poll();
space = maxlen - usbtty_output.size; if(space){ /* Do stuff */ } }
to
/* Not tested */ unsigned int len = 0; while(len > 0) { usbtty_poll();
/* Do stuff */ }
in __usbtty_puts()
puts() I guess _should_ be a 'best effort'. Better, still, maybe we could add an environment variable which would switch puts() between flow-control and 'best effort', so that people have the choice.
/* Not tested */ unsigned int len = 0; while(len > 0) { usbtty_poll(); space = maxlen;
if(environment_variable_use_tty_flow_control) space = maxlen - usbtty_output.size; if(space){ /* Do stuff */ } }
