-# SC_SERIAL_PORT
-#
-#	Determine which interface to use to talk to the serial port.
-#	Note that #include lines must begin in leftmost column for
-#	some compilers to recognize them as preprocessor directives,
-#	and some build environments have stdin not pointing at a
-#	pseudo-terminal (usually /dev/null instead.)
-#
-# Arguments:
-#	none
-#
-# Results:
-#
-#	Defines only one of the following vars:
-#		HAVE_SYS_MODEM_H
-#		USE_TERMIOS
-#		USE_TERMIO
-#		USE_SGTTY
