A while back someone asked on this list for programming code for controlling 
serial ports from linux.  Somebody answered with a slew of C code for setting 
and controlling the serial ports and associated control signals.  I looked thru 
the list archives, but was unable to find this reply.

I'm interested in using the control lines of a serial port turn a camera left
and right when a button on a web-screen is clicked.  Does anyone have 
programming code for controlling the control signals (DTR & RTS) of a serial 
port from linux?

Thanks in advance...
