I'm thinking it was on a 2200 series, but I couldn't swear to it. It
was 1980....

In 1980 I believe that the 2200 & 1100 were the only processors that
Datapoint had out at the time. Your view was 12 rows of 80 characters each.
Invariably green phosphor. ISTR that the 1100s were paired up with 8"
diskette drives, ant the 2200 used dual cassette decks.

Was the display board the serial or RAM version?
The serial display board had a bizarre way of updating the displayed
characters depending on how the program ran it. And it was SLOW. So much
so that when I had to run diagnostics on the tape decks, I would swap in the
RAM display board just so that I could be done in a reasonable time.

I never got to play with them for any length of time because I was a 1 man
remote office, driving to location as repair service was needed.

Depending on what you want. I'm using it at 19200, which is fast enough
for me. I mainly use it for editing, compiling, usenet.

Turning it on and off, switching input, changing channels/volume/etc.
At a ppoe we were maintaing a narrowcasting application, rs232 was used

I'm trying to remember my days of a 386SX/25 in OS/2. My speeds then were
probably limited by my modem (33.6 at best). I don't recall any obvious PC-side
slowdowns like I see on the vt510.

Also trying to remember the days of a 7.16MHz 8088ish DOS box. I guess I didn't
have a modem faster than 2400bps in those days. Still, I think it was able to
run LapLink at 115200 but I may be somewhat mistaken about that, and that may be
a different problem to ANSI video processing too.

I may have to give this a try one of these days.

They had introduced their ARCNET network at that point (probably the
major reason they were picked), so I don't recall any local disk or
cassette storage at all.

I have no recollection whatever. I don't even remember that there was a
choice.

PCs tended to come with a buffered UART that cut down the interrupt
rate no end.

I ran OS/2 2.1 on a PS/2 model 80 baxk in 1991-92, but I think I only had a
2400 baud modem back then. OS/2 could multitask well, though - I could call
my BBS, connect to a MS Lan Manager network and share my files, connect to a
AS/400 terminal session via twinax, and run Word and Excel natively - with 8
MB of RAM!

It was all about the UART with AT-class machines. With my BBS, I had a
socketed serial card and swapped out an 8250 for a 16550 UART and could run
14.4 all day long. I don't recall if my serial card was 8-bit or 16-bit, and
am unsure if an 8-bit card would be the bottleneck on an XT-class machine.

Cheap cards typically came with an 8250 or 16450 UART, which had (I think) a
2-byte buffer. You'd need to either spend more to get a card with a 16550
(16-byte buffer) or if you were lucky, upgrade your existing (socketed) card
by swapping out the UART chip.

The 16450 was pretty much useless above 9600 baud.

The 16550 or 16450? The 16550 came later and added a 16 byte FIFO for
inbound characters; the 16450 supported higher data rates than the 8250,
but ultimately was bounded by interrupt service routine performance.

Then the 16550A came out with the bugs fixed. With them on two 16
port cards I managed to run 32 modems at 19200 on a 50MHz 486 without
dropping a byte.

Did they? I remember buying an ISA card by SIIG with the 16550 UART that
had the huge 16 byte buffer back in 1993 when I got a 14400 bps
modem. With the V.42bis compression I think you could have at least 2x
compression so double data rate over the serial link. Might've had a 486
by then though.

In my computers the built in ports had just the no buffer
16450s. Same with the multi-I/O boards (2xserial, 1xparallel, 2xIDE on
single board).

Maybe the buffered UARTs were common later? I moved away from modems to
ISDN (ISA card) around 1996 or 1997, then ADSL (PCI card) and then
mostly ethernet for communication.

They started to get common around 1994/5 - along with the rise in
fast modem use.

1993, had left IBM ... and was doing work from home. I got offer to do
modem drivers (unix, windows, dos) for PAGESAT in return for downlink
with full netnews feed. I had a RS6000/320 and SGI Indy on my desk and
couple 486 machines (one running waffle, bulletin board software that I
made the netnews feed available on) ... had 16550 UART boards. Also
wrote article on modem drivers & pagesat for boardwatch magazine (had a
picture of me in backyard with PAGESAT dish). Started out 9600, but they
had to double it to 19.2 with increase in images (and there were
periodic further increases).

Digiboards! Those things were awesome.

I ran a store POS system back in the day running Excellenet WAN software.
the hub ran on a 486 running OS/2, the store cash registers either ran OS/2
or DOS. Every night as the stores closed they'd shut down the registers,
close out the tills, and the register would "phone home", sending store
sales, credit card sales info, employee payroll and inventory figures, and
the hub would send back data updates and new price lookup files for the
registers.

I was running a dial-up BBS back then, the store-and-forward topology was
reminiscent of Fidonet. I'd often thought you could do the same thing with a
Fido mailer and save a ton of money.

The batch files running the stores were written in DOS Batch or REXX,
meaning if you fat-fingered an update, you were walking a non-technical
store manager through using a line editor over the phone to make the fix.

At certain times of the day, I'd have 32 14.4 multitech modems lit and
transferring files, and it worked like a charm.

Correct, they were indeed Digiboards.

It happened at 6pm on the dot every day for me, when the evening
cheap phone rate cut in - I was running a dial-up ISP.

I was once in Demon's Finchley office at 6pm and got to see their
bank of modems (90 or so at the time IIRC all running on a Sun box with
SCSI attached serial[1] ports) suddenly light up in a ripple across the
rack right on the dot of 6pm.

[1] Of course these days we have serial attached SCSI.

trivia: circa 1990 , IBM Hursley did 9333, SCSI disk drives ... with
serial copper running packetized SCSI protocol, originally was
80mbits/sec full duplex (160mbits/sec aggregate). 1988, I was asked to
work with LLNL on standardizing some of serial stuff they were playing
with, quickly becomes fibre channel standard (initially 1gbit, full
duplex, 2gbit, 200GBYTE) I had hoped that 9333 could morpth into
interoperable 1/8 & 1/4 speed FCS, but instead it morphs into SSA

"twinax". Now there's a word I haven't seen, in that context, for awhile.

I worked for a manufacturing company that finally got off the AS/400 in 2005.
That twinax was never removed from the walls, and it is the kind of stout stuff
that will probably be around until the sun goes nova...

I had a real moment of confusion when I first heard of Twinax being used for
10Gb copper Ethernet. Weird echoes, that.

I ran 4 channels on a '186 along with networking once on an embedded
