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.
