Perhaps.  More relevant is that USB/Serial (or parallel) adapters  
don't adequately emulate or support all the IMPROPER ways of using a  
port that used to be so popular.

We ought to develop and standardize a "bit twiddle" USB peripheral so  
that we can still put all sorts of random hardware out there and talk  
to it.  Alas, once you have to buy or build a special device like  
that anyway, the twiddled devices become a lot less attractive.  They  
USED to be neat because you could connect something made of jellybean  
parts to a standard PC for very small cost.  Remove one of those  
pieces, and you might as well buy a picKit2...

I used it to establish a dialup internet connection through a nokia 8210
mobile phone once (old school gsm dialup, 9600 baud). For some reason
though the connection seemed to hang as soon as anything more than the
most trivial ammounts of data were transmitted (email just about worked,
web browsing didn't)
.
I have also used it to print text messages from that phone direct to a
suitable printer.

Yes it does (of course when you're looking for twiddleability you
probably want TTL and not RS232...). It also has the ability to
arbitrarily twiddle 3 of its pins (PGC/PGD/AUX) to TTL levels or
tristate and read them, completely ignoring any "protocol".

Running something else then Ethernet ?
