You'd have to replicate most of what tty_io already does, and that seems fairly pointless and fragile. Any change to that subsystem will likely blow your driver's duplicate logic away. > Given my limited experience in driver design would you recommend rewriting > the driver as a tty driver (I'm guessing this would involve interfacing with > tty_io.c) or is there another way?

If it were mine, I'd take a look at one of the existing tty hardware drivers (drivers/serial/21285.c looks simple enough) and use that as a template. -- James Carlson 42.703N 71.076W <carlsonj@xxxxxxxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-ppp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
