Yep. I use them all day, every day, and have never had the
problems I've heard people complain about here. Right now on my main
desktop machine, I have a USB<->serial adapter connected to an ARM9
development board, another connected to a homebrew Z80 SBC, another
connected to a PDP-11/83, and yet another connected to a PDP-11/70.
They all work wonderfully. I use Keyspan adapters.
Admittedly, though, I've not tried my old A-J acoustic modem.
Some people whine about they Keyspan adapters being too
expensive...they may be having problems because they bought some
cheap $5 adapters. The last Keyspan unit I purchased cost me (I
think) about $30.00, and I bought it about six years ago.
Complaining about $30.00 over six years is being too damn cheap, even
for the cheapskates around here.
On my Sun Ray thin clients, I use Edgeport quad-port adapters.
They exhibit some latency (that may be due to the Sun Ray USB
encapsulation though), but they work pretty well otherwise. The
serial ports show up as devices on the Sun Ray host system.

I think there
has been other threads here regardng the hit-or-miss
nature of these USB-to-serial adapters. I know when I needed one
to sync a Palm, I couldn't find one that did it right. I think
I hit my head against three $30 adapters to no avail, but this
was four-five years ago.
I've used them to talk to terminals and had no problems.
