Serial port performance did not scale well on early pcs, so an industry was
grown with smart serial cards. There were a few serial cards, but most
 didn't have the smarts, just shared interrupts. Best performing, in my
usage, was the Stallion brand, an Australian company. These cards had their
own processor, uarts and ram. Had used 4-32 ports. I am guessing they did
high speed transfers via the high speed bus on the PC, relieving the main
CPU from getting interrupts, doing queuing, caching etc. These cards were
supported by SCO products like Xenix and Unix, some others and ran on a PC.

Flying aircraft could be efficient for some visits that didn't have direct
city pairs served by airlines, especially the US. Plus a lot of fun, if you
do it yourself.

I used to push statistical and financial data around Australia in the 80s
via dial up using automated scripting with Zmodem, Sun hosts, PC remotes.
Was very reliable.

IBM NDAs and legals can feel overwhelming in meetings....
