  Minicom has an option 'Q' which will quit without resetting either the 
'modem' or the serial port.  I've used minicom to open and initialize a 
serial port, test the device on the other end, then after exiting without 
reset ('Q'), sent bulk data to the device with `cat <filename> /dev/ttyS0`

Conversely, minicom has a command-line option '-o' which will bypass modem 
initialization on startup, but it still initializes the serial port.
