Couple of memories here triggered by the mention of fax machines.
Back in the 90s I worked for a Stockbroking firm that still had a Telex machine ! We had one client in India who would send through orders on it and when it burst into life, people would nearly have a heart attack.
We did have someone who was p!ssed at the company do the old looped page through the feeder to use up all the paper in the fax but fortunately it was a plain paper fax, so once the tray ranout, it just held the job in memory. When we came in on Monday, we killed the job and let it print out the next queued jobs.
Recently had to set up a fax machine for a doctor's surgery, when we asked why they wouldn't use an online service they said they preferred to use the device they had so they could confirm that faxes had gone through :) Because it was connected to a 3CX pbx we set it up to deliver received faxes as emailed pdf files .
