Is showing all attributes for RS232 port possible in FreeBSD?

[Garrett Cooper]

Hi,
	I was just wondering if there was any way where I could program with  
C, such that I could view information regarding the extra pins on a  
DB9 serial port other than just TXD and RXD, ie the DTS, CD, CTS,...  
etc ports.
	I am trying to figure out how exactly Hyperterm works as part of a  
project with programming a PIC microprocessor.
	Thanks!
