Obviously, I modified the order entry and wholesaler systems to work with each other.

Luckily my 50 line receiver only had to deal with 1200 baud, but it did have to transparently deal with 7-bit even parity, 7-bit odd parity and 8-bit no parity. //

baud rate was simple: 115200, 9600 or occasionally 1200

115200? Hark at Mr Fancypants and his expensive toys.

occasionally 1200

Occasionally? You mean you let your expensive modem just sit there unused? Wasting all that time getting the occasional table close enough to the 'phone inlet so the two could connect!

Next you'll be telling me everything ran at 8N1! //

Back when I was a lad, we fought in the gutter to get 110 baud connections. //

Luxury! We didn't have baud rate, we had pigeon rate and we was happy to have it. //

You had pigeons?

We just had stones to throw. Made for pretty short range transmissions.
