Question: Serial port device drivers...
I am trying to develop a device-driver to sit above the standard serial port - in other
words, multiple processes can communicate with the driver which will translate the
information into the required serial datastream for the device. (This could be written
as a separate daemon-type process, I know, but as a kernel driver it will fit into the
scheme of our system in a much neater way).
I haven't found any other drivers in the kernel which quite do what I want, and I don't
particularly want to make a copy of the entire serial driver code and put the mods into
that (seems like a waste of space). Essentially, what I need is to have a relatively
simple driver which just calls the standard serial port routines to send/receive data.
Has this been done before, and does anyone have any sample code or hints as to what I
need to do? We are using kernel 2.2.16 (from RedHat-7.0).
Regards,
Wayne

You might want to take a look at the Axis Bluetooth stack for Linux (www.axis.com). It lives above the serial driver and sounds like it does what you are looking to do.
Hope this helps,
