They are called a "terminal server". It's a box with some serial ports and one Ethernet port. You access each port via "telent protocol". You can buy these surplus on eBay or you can MAKE one very easy. All you need is any kind of small computer, a 10 year old notebook PC, a Rasbury Pi, or whatever, so long as it has both a network and a serial port. Run a Telnet SSH server on this and you are on-line and can access the device from any place on Earth. I would not buy a small computer for this but if you have one already then it is free. Telnet is very old. I remember using it first in the late 1970's back when the "Internet" was still called the "Darpa Net" and it only connected a few dozen computers. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
