As I learned long, long ago (in what seems like a Galaxy far, far away) during my [first] career;
When troubleshooting a communications system walk the ISO model.

The comments page looks so... empty... fragile.. vulnerable... I wonder how many comments will there be already when I finish posting this.
Admin
I would have expected something like the 500 mile email ...
But well, we take what we get, right?
Admin
this sounds like SOP for the mid 80's.

So... multiple phone lines for each PC, plus all the hardware was more efficient than the leased lines, just so they could run 3270's?
/boggle
Admin
It's very possible that this setup was a reasonable thing to do. Leased lines were quite expensive.
Admin
I hope he kept a sharp ear out for banjos in those backwoods.
Squeal like a pig, computer boy!

It's a more efficient use of the company's money for sure. The PCs are a one-time sunk cost or perhaps a depreciating three-year lease, same as the terminals would've been and probably not much more expensive.
POTS lines are cheap compared to leased lines where you're (in principle) paying the phone company to set up and maintain a piece of copper between two points that exists solely for you.
Admin
That 8087 was inappropriate for its purported purpose. Apparently nobody told management that accounting should be done in exact integer/decimal arithmetic, not floating point. Unless somebody was also doing a little Superman-style penny-shaving.
Admin
That should have been "squeal like a 300 baud modem!"
Admin
I worked at Coney Island Hospital in NYC at the time when they were rolling out their "upgrade". They switched from dumb terminals to windows 98 running terminal emulators.
Support calls went from a dead terminal once every week or so, to "My Computer is frozen" several times a day.
They couldn't at least go to NT 4? I mean seriously "Windows 98"?
Admin
Surely a multiplexer and a single modem line would be enough to replicate all of the dumb terms. What's the point of having a very expensive modem (damn, in those 80s even a 300 baud was an arm and a leg) for each PC?
Admin
As if NT4 was any more usable. Sure, it may not have crashed as much, but user training would have been crazy.
Admin
In other news today, a $25 computer is emulating not just a 3270 terminal, but the whole darned mainframe: http://www.designspark.com/content/my-raspberry-pi-thinks-its-mainframe
Admin
If it was truly that back woods, how were they technologically-advanced enough that they could use touch-tone to reach the long-distance operator?
Admin
First!
Greetings from Alabama
Admin
That's called progress. Now let me do some actual work at the VT100 emulation I run on a virtual manchine in my 8GB of RAM six core PC.
Admin
Um, wouldn't an acoustic coupler work in that situation?
Then again, training might have been a nightmare.
Admin
"When the computer attempted to dial out, he heard the sound of touchtone bleeps followed by a crackly voice saying, "Number please.""
I pity those poor telephone operators who got prank-called a hundred times with strange beep noises while they tried to get this to work.
Admin
Still kinda slow down there, eh Lyle?

I once was sent to install an IVR system in a city that didn't support touch-tone dialing ...
Admin
In a phone system without direct-dial long distance, it seems unlikely that they'd support touch-tone dialing.
Admin

They probably didn't.

There ain't such thing as promotion coments anymores. :(

My clue is Alex is being lazing around now everyday. He ain't caring about this website for now.

Adding up debits and credits should be materialized into whole pennies, absolutely. But if you're calculating a monthly payment on a loan, or if you want to do some forecasting, floating point is appropriate.
Whether this is "accounting" or "finance" is an open question, though.

Part of the phone system easily could have moved over to tone dialing, yet still had some outdated infrastructure. I lived in NC in the early 80's, and while we had people using modems for BBS connections, and yet we still occasionally ended up on shared "party line" calls depending on the area of the county, who you were calling, etc.
Admin
Sting? Are you DAFT? Hope I don't have to submit a DailyWTF based on your code! I would just love to debug code that performed dollar amount calculations in strings, that would be just lovely!
Of course they teach numerical analysis in American College Courses! But obviously, you failed "English"...

I'm the OP. Actually the computers were 8 Bit CP/M machines. They were custom built for our company (a WTF in itself). There were only 4 per plant so they just shared a dial-up phone line. It was very slow because with every screen it waited for the line to be free, dialed the mainframe, connected, submitted the request, received the data, and hung up.
My boss called in some favors so we were able to give some of the users two computers. That way they could type into screens on one PC while the other one was waiting for the other to connect and transmit.
The users hated the new setup but it did save a LOT of money by eliminating the leased lines with 3275 terminals. Leased lines were very expensive then. I wasn't privy to the figures on whether we were paying more for overtime than we saved on leased line costs.
Most of the towns where we had plants did support touch tone dialing and direct dial, but one didn't. The phone company there was very small with only a couple of counties as it's franchise. We could configure the modem to dial using clicks instead of tones, but it wasn't possible at that location to make long distance calls or calls to toll free numbers without operator assistance.
Prior to installation we contacted the phone company to make sure they supported direct dial and they said that they did. Of course, when we pressed them on that point they said that they meant that they "planned" to support it.

Could you have done some sort of proxy thing where the one backwater town calls one of the other towns locally, and the second town calls long-distance to wherever the first one wanted to connect to?
Admin
Modems always have supported Pulse dialing for "Alabama-level" telephone systems.
Admin
Wondering if it would have been feasible to have an acoustic coupling type modem and a handset, call the operator on the handset, give them the number to call long-distance and when they connect the call put the handset in the modem coupler and get the connection going. I've had to use similar workarounds to make long-distance/international fax calls with a calling card, dialing manually then hitting "start" when the ring-tone comes through.
Having to do that every time you needed to make a connection would have gotten real old, real fast though.
On that note I guess the "drop the connection after every screen" feature was at least partly inspired by the need to avoid racking up long distance charges while reading the contents of a screen. I used to live somewhere that had per-minute local call charges and when I first had dial-up internet I would connect, transfer mail and newsgroups messages, pull up any web pages I wanted to read, then disconnect while I read them. I do NOT miss those days.
Admin
I can actually imagine modems incorporating a "workaround" for these situations: the digits 0 to 9 prerecorded, played back in the necessary combination when they find a human.
That might be too advanced for a little 1980s modem. You'd need to incorporate a cassette player and all that.
Admin
Didn't musical greeting cards exist in the '80s? They could have used something like that. It doesn't have to be especially clear, since none of the digits' pronunciations are that close.
Admin
In 1988 at univarsity, I need to write workaround for java.net.URL because it ain't working whilthout physical conection for destination.
Admin
Dammit, that was what I was going to say.
Admin
And when I read that, my mind immediately said, "Sure, AT DP". I'm sure glad I remember Hayes modem commands, even though I haven't coded commands to a modem in about 20 years. Acoustic couplers are coming back, you know. This broadband thing is just a passing fad.
Admin
RE dialing by hand: This is exactly how we did it when I was in high school. We had to call the school operator, get an outside line, dial in, wait for the carrier tone, and then put the handset into the acoustic coupler. It was awkward but it worked fine. But yes, if you had to do that for every screen, that would get real tedious.
RE long distance charges: That's why there were WATS lines, which stands for "Wide Area Telephone Service" or something ilke that. You paid a flat monthly fee for unlimited long-distance calls. I guess incoming WATS is still around: that's what an 800 number is. I don't know if there's still outgoing WATS. Cell phones these days tend to charge the same rate for local or long distance, it looks like that distinction is going away.
