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).
