And somehow this thread has avoided the obvious "FTDI vs Prolific" flamewar! Basically, those are the two USB-to-serial chipsets on which all devices on the market are based, and some people swear both are awesome all the time, and other people claim one works better on Linux than the other... Maybe someone can remind us which is which...
Also, this thread has missed the obvious "The USB equivalent of a null modem cable is this: https://www.amazon.com/Plugable-Windows-Transfer-Computer-Software/dp/B005OTPVMY";, but I have literally never known anyone to use one of those, on Windows or Linux, and have no idea how one would even approach the task... Also, while I agree with everyone that Ethernet is DEFINITELY the way to go here... And, I DEFINITELY think USB->RS-232->null modem cable->RS-232->USB is an epic pain in the ass with no measurable gain... I have actually done file transfers over RS-232 null modem cables, in the distant past... Both computers had native serial, as was the custom for the time... But one had a DSL internet connection, and the other... Well, it spit in the face of the "Computers with USB always have Ethernet" claim thrown around here... So, I initially used a terminal client that could serialize files and send it to another terminal; It worked, but I wanted more. In those days, PPP-over-Serial was a prominent feature in many commercial OSes, and I was able to cludge together some simple internet connection sharing. It worked... Albeit, only as an academic study, a proof that the text books weren't lying to us so to speak, as one couldn't even imagine using that crap in production, even in those days... Of course, that's why some USB-to-serial interfaces offer a "net-interface" emulator... It effectively masks away all of the software ugliness by treating it as a simple Ethernet adapter. On the other hand, if that were a solution you were willing to accept, then Ethernet is DEFINITELY better in EVERY SINGLE metric (Even the made up ones you refuse to actually say out loud). So... I foresee lots of reading about "Terminal Node" software in your future. Of course, the only folks still playing that game use ham radios instead of null modem cables... But the broad concepts and important details are the same. Good luck, and may the Lord have mercy on your soul... On Fri, Jun 1, 2018, 03:38 Richard Owlett <rowl...@cloud85.net> wrote: > Who? Me?
