I maintain our own version with a patch to deal with multiple usb-serial adapters (correspondance between physical devices and /dev/ttyUSBn nodes is quasy-random, instead of /dev/ttyUSBn names I use USB path names, then grep through /sys/class/usb tree to find the right ttyUSBn node). http://daq-plone.triumf.ca/SR/ser2net We also use ethernet-serial adapters, but I forgot which brand, we have not purchased any recently. Note that you have to use them on a private network or behind individual firewalls (unless newer units have built-in firewalls). -- Konstantin Olchanski Data Acquisition Systems: The Bytes Must Flow!
