I am trying to get a CrystalFontz 632 serial display to work with an OpenBSD box. Under Windows I can just connect the display to a com port, run Hyperterminal and send text directly to it, so I assumed that I could just send a data stream to /dev/tty00 under OpenBSD and make it work as well. Unfortunately it is not turning out to be anywhere that simple.
If I use cu or tip and connect to /dev/tty00 and 19200 then I can send data to the display, but eventually I need to be able to send data to it from a shell script. Any attempt I make to send data to it (such as cat test > /dev/tty00) results in an error of "sh: Cannot create /dev/tty00: Interrupted system call". I've tried to mess with the stty command to setup the serial port (open it up, set the speed, etc), but no luck, that error always comes up. Can anyone point me to the right direction on this? Thanks, Peter
