Exactly.  A PC is typically limited in terms of how many ports
it can support -- regardless of the aggregate data rate.

OTOH, you can open a socket per "virtual serial port" and handle
scores of low data rate transactions in one appliance.  And,
your PC can be on the other side of the continent!

[I like the single port terminal servers to talk with my
legacy peripherals, here.  Also has the advantage that *any* PC
can connect to them instead of being hardwired to *a* machine
with *a* serial port!]

It's only a matter of time before we see everything with a network
interface (wired *or* wireless).  All these other efforts will just
be seen as distractions -- effort wasted pursuing half-assed
solutions.
