2b88677895 system/cu: do not reset baud rate to zero when parity options are used
cfsetspeed() now stores baud rate to c_cflag member of
struct termios, so it must not be overridden later on.

fcd3937d7c system/cu: refactor, add option -c to disable \n -> \r\n conversion
option -c will disable \n -> \r\n conversion both for serial device and console if it is a tty

refactor: use only one function to set termios parameters, use termious related code and options only if CONFIG_SERIAL_TERMIOS is defined

dabe412e70 Add a minimalist implemention of the 'cu' terminal program (part of Taylor UUCP for ages). Using it, you can simply open a serial port and interact with it. Using '~.' you can leave the terminal program and drop back to nsh.
This might  come in handy for other people that have e.g. GSM modems, GPS receivers or other devices with text based serial communications attached to their Nuttx systems.
