Assuming your camera is RS232, you can use a simple RS232 daughter card on the Raspberry (about $7 from MCM electronics and others). I have done this exact thing for communications with an old RS232 device. Alternative is of course a USB to RS232 adapter and as Greg writes, you just change the target device file (the $7 adapter also creates a /dev/ttyxxx device. -Bruce On Jul 21, 2014, at 12:18 PM, Greg KH <greg@xxxxxxxxx> wrote: > On Mon, Jul 21, 2014 at 03:19:00AM +0000, Amadeus W.M. wrote: >> Not sure if this is the right venue for this question, please direct me to >> the right place if it's not. >> >> I have a C program that opens the serial port /dev/ttyS0 and sends commands >> (as strings) back and forth to a pan-tilt-zoom camera.
