19200 was a very popular speed back then, when 9200 was too slow,
the cables became shorter and "RS232" was tweaked and hacked to
fit the PC landscape (short cables, lower voltage swing and things).

Then modems became faster, because of more sophisticated modulation
schemes and the last mile becoming shorter and shorter [1].

Ah, good ol' times :)

Cheers

[1] Miles don't become shorter. But as most customers live in
   densely populated areas, last mile providers discovered that
   the others "just don't exist" unless the government shells
   out money for them. Which is used for many other and Ponzi
   schemes...
