After browsing the support sites of Lantronix, I think I found the software I need: The rtelpd daemon process is used to provide access to serial or parallel ports on a terminal server. A named pipe is used as the actual interface to host based appli- cations. These applications can then communicate with equipment attached to the server as if it was locally attached to the unix host. I can create a /dev/somepipename device with that tool. I need this rather unconventional method because we have several remote sites that are connected to the center via public digital lines (64k). Multiplexer on each end offer up to 16 transparent serial RS232 ports. Via the ppp link we get access to the network in the center- it's slow but sufficient for our application. The NTS is only needed in the center because it offers 8 ports. I find this more elegant than upgrading the Ubuntu- Server with additional serial ports. -- View this message in context: http://www.nabble.com/Using-an-NTS-instead-of-the-local-serial-device---tp14532384p14533230.html Sent from the linux-ppp mailing list archive at Nabble.com. - 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
