Like a named pipe device. What you're talking about is pretty much the existing pty device. Unfortunately, Linux pty's only support a subset of the serial port API, so they can't be used for applications like network-connected serial ports. So people like me have to write kernel-mode drivers for such devices. I've suggested extending the Linux pty so that it _does_ support the rest of the serial port API. I even offered to work on it if the results would likely be accepted into the kernel tree, but my questions/offers have never gotten any response. -- Grant -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
