I am looking to find a simple way to control a serial port through BSD
(such as raising and lowering DTR for a specified duration). I thought I
had it using ioctl() and wrote a simple program to test it, but it seems I
don't have a full understanding of ioctl(). Does anyone know of any
pre-written utilities I can use? Or where to get some really detailed
information about ioctl()? Thanks!
