(NOTE: FSK RTTY with this hardware combination does *NOT* work with
DM780!) The other serial port does work with CW on N1MM+, CWType and
even DM780.
DM780 is "brain dead" when it comes to FSK in that it will not allow
both PTT and FSK on the same port - although it allows both CW and
PTT (figure that out <G>). However, if you configure HRD to provide
PTT either using the RTS line of the CAT port (if your radio/interface
supports it) or by using CAT/CI-V commands and configure DM780 to have
HRD control PTT you can use the same configuration for both N1MM+/MMTTY
or HRD/DM780.

I have to start out by saying that I am not familiar with that Startech
box, but if you are using a desktop, you may want to consider installing
a serial card. When computers stopped coming with serial ports, I
installed a dual serial card in my desktop rather than mess around with
USB-to-serial adapters. The one I bought was from Newegg and cost about
$12 (including shipping from China). My computer originally came with
Windows 8.1 and the serial card installed with no issues (once I went to
the manufacturer's website and got the latest drivers). I upgraded(?) to
Windows 10 last year and it survived the transition with no issues.
For the interface, I built the W3YY interface kit
(http://www.w3yy.com/fsk.htm). My radio is an IC-7410 and I can report
that FSK RTTY works flawlessly with MMTTY and N1MM+. (NOTE: FSK RTTY

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?
