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.
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.
Likewise, I have never had a problem - for me they Just Work (tm) -
Now to admit my dirty little secret... Just use the TX/RX/GND Lines,
and tie RTS-CTS, and DSR-DTS-CD (At each end of the cable) - Hardware
handshaking never quite works the way you expect it to!
