Here is my problem:
	I am trying to control a digital disk recorder remotely by sending
it commands through its RS232 port.  I want to use a Tektronix 4301 computer
which is using a Tektronix modified version of 4.2 BSD to send the control
messeges.  Using a VT340 terminal I have sent commands to the recorder 
through the RS232 successfully, using 8 bit, even parity mode.  However,
the Tektronix is sending out 7 bit bytes.  I have been researching ioctl
commands to change the port to sending 8 bits, but have not had any luck.
The port I am trying to use will be exclusively for interfacing with the
recorder, so I can modify anything about it.  I am looking for any advice
as to how I can change this port to 8 bits, whether in unix shells, changing
device characteristics, or C programms.  

Please e-mail responses to jeff@theory.tn.cornell.edu.  Thanks.
