Hello I have a serial port accesible via Ehtercat. http://www.beckhoff.dk/english.asp?ethercat/el6001.htm Ethercat is a fancy way of accessing i/o devices via ethernet. You can read/write registers with close to real-time restrictions. Nowadays there is a kernel land implementation of ethercat master, but it is not merged (and it is definately not an easy job). And a software implementation http://fh-soft.de/src/ethercat-userspace.html My hope is that there is something like uinput, but for serial devices,i.e. I make a userland program that looks like a normal serial device to the other applications. Does this exist? Regards! -- Ricardo Ribalda
