Well, FWIW you *can* read and write the control lines using the
TIOC_MGET and TIOC_MSET ioctl calls. I have no idea if the Linux
serial drivers support the full gamut of -232 control lines (I know
IRIX and Solaris don't).

Also, issuing a lot of ioctl()'s might limit the speed and reliability
of this (really sick) interface, so doing a kernel driver might be the
only viable way... :(
