Hi Kim,
I don't have any experience with that particular adapter. Until now
I've always used a 4 port UART board in the desktop as someone
described earlier. However, I'm considering getting rid of the desktop
and replace it with a laptop. I just finished building a new interface
(which I call the Amazon Special) that only requires a single USB
port, and provides for CAT, Audio board (Behringer), groundloop
isolation through transformers and optocouplers, and FSK keying using
the TinyFSK solution by Andy Flowers, K0SM:

It seems to me that folks only really struggle with serial port
solutions when it comes to FSK keying, so I'd really consider the
TinyFSK solution. It looks to me that it can easily be adapted for use
with the K3S and you won't need W1AN interface I think, if you add a
DB15 connector to the TinyFSK interface. The web page describes how it
can be used with N1MM.
I tested the TinyFSK interface with Airlink Express in the SCC contest
and it works just peachy. Airlink Express (not contesting software!)
will have native support for the TinyFSK in the next release.

I have a Startech ICUSB2324X USB to 4 COM port adapter that I want to
use with N1MM+ and the MMTTY engine to key FSK and PTT through the
W1AN interface that plugs into the DB15 connector on my K3S.
This Startech adapter was recommended by a local RTTY contester who
uses it without problems on Windows 7. I'm using Windows 10 64 bit.
The drivers installed OK and I have 4 active COM ports (5, 6, 7 and 9)
in Device Manager. I decided to get this working with MMTTY by itself
before loading the MMTTY engine with N1MM+. I have COM5 (first port
on the Startech box) cabled with a straight thru cable to the DB9 end
of the W1AN adapter. When I set MMTTY Options TX for FSK and select
COM 5 and hit OK, MMTTY throws an error that says it can't open COM 5.
Changing to another COM port gets the same result.
Now here's the weird part. I configured MMTTY and the K3S to use the
USB sound interface built into the K3S, and that works fine with AFSK.
I left the serial cable connected. However, when I transmit, I noticed
that the PTT line on the W1AN adapter is activated by MMTTYand keys
the K3S!! The red LED on the adapter is on. If MMTTY can't open open
the designated COM port, how can it toggle RTS?
Anyone have suggestions on how to get this working or experience with
the ICUSB2324X adapter?
