We still have a client who sends us DBF files once a week. This is using zmodem on a 14.4k dialup.
No idea what the hell they are sending this from. We dared not ask but they pay us a metric fuck ton of cash to keep this alive. Everyone else is using CSVs and SFTP.
We actually bought some Hayes modems off eBay incase the current one packs in.
Ha!!
. I liked the "Metric F@#$ Ton of Cash" part....
Not knowing what services your company offers, and the nature of the 'business' sending the data to you,
it would be hard to ascertain the reasoning behind their 'methodology'
Maybe they are just 'Old-School' and like it that way. Maybe they think it is 'safer' that way, avoiding more modern 'norms'.
Interestingly, where I am, in Australia, (not completed Nationally yet), we are now on the new "A.B.N.", (Australian
Broadband Network), which is all new 'Fibre-To-The-Node' as a minimum. There are NO 'Land-Lines' as such, when on
this new fully digital system, and the 'equivalent' to a 'Land-Line' is the new Routers using something like 'V.O.I.P' !!!
So the OLD 'Dial-Up' Modems would instantly fail miserably now
However, Aahhh.... don't you miss the 'Old' "Beep-beep-screech-beep-screech-screech" of the old analog 'Modems',
before they decide to 'handshake' with each other and then go mysteriously 'silent' as they continued to 'converse',
at a whopping 75 or 150 K-bits / sec... Sigh. And the 'Voyager Space Probe sent an 'LP' Record for our Alien friends !!
BUT... all this 'old' stuff still works in theory/practice, and was simple xxx, just lost now in the youthful hands of smartphones
