Re: [Elecraft] OT Ethernet/RS-232

Hi, Forgive me, Eric, for adding one more post to this thread, but this is not to reignite the "why are we still using RS232" question. Rather, nobody has mentioned one good reason to use an Ethernet to serial adapter. It extends the range to several hundred feet, something neither RS232 nor USB c

Re: [Elecraft] OT Ethernet/RS-232

This is not exactly true. RS232 is still widely used over long haul RF links, telemetry and scads systems. Why? It's reliable, it just works, you don't have to stuff around with drivers or custom software and its a self recovering system. USB is a vendor driven platform. There are very few "uni

Yes. I just had to replace the old tower with a new one. I told the "computer boys" who we deal with to put a "real" RS-232 port in it. I should have told them "Two please." On 11/27/2012 2:59 PM, Bill Frantz wrote: I don't think there are any new laptop computers with RS223 ports. Are th

Re: [Elecraft] OT Ethernet/RS-232

Thanks to the many people, both on and off the list, who pointed out current uses of RS-232 in industrial systems and datacenters and the limited availability of RS-232 interfaces on new computers including laptops. Indeed, there is nothing that is completely obsolete in electronics and compute

Re: [Elecraft] OT Ethernet/RS-232

This has gone in a direction I was afraid it might and tried to forestall. My only intent was to mention an affordable device that would allow you to have an RS-232 connector at a remote location. Thought it might give some ideas and options to those who wanted to easily control devices at a di

Re: [Elecraft] OT Ethernet/RS-232

I would say there are many many more computer to computer connections over TCP than over RS-232. And many more over PPPoE . As far as I can tell, hams are the only users of RS-232 left. (RS-232 has the wonderful advantage of ma

Re: [Elecraft] OT Ethernet/RS-232

David, I would submit that RS-232 is still the common denominator for point to point computer communications. No licenses, no registration, no unique IP addresses, just "communicate". That converter from Ethernet to RS-232 may prove to be useful, but most radio gear will continue to use RS-

[Elecraft] OT Ethernet/RS-232

Not wanting to resurrect the why still RS-232 arguments I still thought this looked interesting. Didn't investigate enough to see if it would work with a K3. Thought there might be someone who would find it useful for something. There is also a multiple
