This is actually a good reminder to us technologist that technology isn't everything.

[Yeah, I researched these back then.  I had to explain why EDI was worth doing...]

There was a time (around late 1980's to 1990) when fax was everywhere, yet official documents (such as purchase orders, letter of intend...) were send via telex.  The world has yet to catch up operationally -- specifically, legal standing of said documents.  Telex has been around for decades and by then, the legal requirements were well developed thus better supported by legal codes.  Both national and (some) international laws made telex equal to that of a signed letter.  So, (depending on where you are)  if you get a fax for an order of 100,000 units and the guy backed out of the deal, you have no protection whereas, if you get the same order via telex, you have the legal equivalence of a signed purchase order and can sue the guy for default.

EDI started around just after WW II but not as widely used as telex.  By 1990, EDI (x12) caught up with telex and then some.  EDI gained legal standing with EDI Service Providers being a 3rd party proof.  You send an order via EDI, your EDI Service Provider has "data retain rules" and such data can show you did received said document as you claimed.  The sender's EDI provider also has collaborating data.  So it became easier to deal with legally. Around mid/late 1990, (I think Singapore was first, then Hong Kong and then the rest of the Asean ports) you could do port of entry custom via EDI custom declaration so processing begins before your ship even docked.  Email was popular then, but back then if you send Singapore Port of Entry an email of your Bill of Lading and expect them to process your cargo for entry, it would of course go no where.

Even today, with all the email, fax, whatever - By law, I have to bring a hard copy for some prescriptions before a pharmacy can fill it where as some prescriptions can legally be handled by fax alone.  (That hard-copy required prescription was for some post-operation heavy duty pain killer which contains Opioids).  Even my veterinarian(cat doctor) knows email sender id can be faked.  So my veterinarian takes (with caller ID) fax prescriptions from my other veterinarian (eye-specialist) but not prescriptions via email.  (Yeah, I have my local vet fill the eye-specialist prescription to save the long drive to the specialist.)

Back in the day, Management decided it would be a wonderful thing if manned TV & Radio Broadcast sites sent a daily report to the appropriate State Headquarters.
To this end, we were supplied with Telex machines & a tape reperforator.
After a while, we discovered that, using the "reperf" we could make up template tapes with the repeating stuff, run them, stopping & adding the appropriate stuff for that day's report, as needed to produce a new tape for that day.
We got pretty slick with this & the Telex system was fast & reliable, very rarely needing a 'resend".

Management then fell in love with Faxes, & we had to use them instead.
This entailed, either using an old "clickety clack" typewriter, or writing the report by hand.

The real trouble started when we tried to send the Fax.
It would almost always fail on the first try, sometimes on every try.
Compared to the almost trouble free Telex, it was a nightmare.
