Subject: Support nonstandard (not yet all supported) flow control options. 
 `ctsflow' and `rtsflow' are the components of `crtscts'.  `dtrflow' and
 `dsrflow' are new and not yet supported.  `dtrflow' may be useful for
 Cyclades serial careds, which have h/w support for it and no h/w support for
 `rtsflow'.

print.c:
Report NTTYDISC in case the line is in this obsolescent state.
