    Cool Raw serial control in Linux

    Greetings,

    Back many years ago, I figured out how to control the pins of a serial port independently under Win98 in VB6. IE, rather than writing data to the port, I could set two of the pins low or high as well as read the input state of three different pins.

    Does anyone know how to do this in linux? I know how to bit-bang a parralel port so bit math is no problem... I just can't find documentation on doing any sort of serial control on linux other than streams.

    Thanks in advance,

    Good coverage of serial programming in Linux: http://www.easysw.com/~mike/serial/serial.html

    There is access to several pins, but not all (like Rx and Tx). Anything not provided by the existing driver means you would have to write your own driver.
