Additionally, I tend to write comm drivers/handlers that are
more generic.  I.e., that support full-fledged ioctl(2)'s.
So, I can choose to configure the device to support XON/XOFF,
RTR/CTS, breaks, bit rates, parity, etc. from the application layer
AT RUN-TIME, based on the needs of the user's peripheral equipment.

In that way, I don't have to keep reinventing the same wheel.
