OK we are keeping a few win 7 systems but the workstations we were given
this week that have 7 are going up to 10. 10 will have the longest
active license period... despite flaws now... they have a while to fix
them all!

Well, winblows is what it is, though I am stuck with it for a while (only
windows 7 though, as I have disabled MS hacks to force W10 on my machine).
Here is the current sucky issue I have found: pair a bluetooth rfcomm
device, connect and test, and un-pair. Repeat for about a hundred times until
blue-screen-of-death. I presume usb com port shit is similar.
So, when I un-pair a bt device (using an rfcomm port, which turns into a
win com port) I expect that the win com port has been relinquished and
released back for use. But no fucking way. Win, in its infinite wisdom, keeps
going until com ports hit a hundred or so and then it just pukes.
However, Ladyada (Limor Fried), of Adafruit, pink-haired engineer
extraordinaire, posted this hack:

You still need to right-click and delete every frickin' com port
individually, but it works to get your machine running again.
Microsoft, you still suck at writing operating system code. Shit. Ain't
that your business?

Thanks for the detailed write-up. I'll add your observations to the notes
I have online for setup. On Windows, it seems like having some other
program trying to occupy the COM# device is an occasional problem.
A quick note, in "notranslate" mode the device is basically a transparent
passthru, so other settings (like unshift on space) won't have any effect,
since the adapter isn't keeping track of shifts in that mode. It does no
harm to have it set, of course.
Sorry about the tight clearances on the mounting holes. I only tried it
with nylon spacers.
Oh, and in heavymetal you could try editing the heavymetal.cfg file and
removing "TTY.1.BaudRate" and it might not be so insistent on trying to set
up the serial port parameters, which aren't needed for this board. I forget
if it'll allow you to do that. Also if you want to enable unshift-on-space
you could do it in the heavymetal config, since that's where the shifts are
being kept track of when set up this way - use "-TTY.1.UnshiftOnSpace=1" in
the config file.

Received the new USBTTY board a couple of weeks ago and finally had some
time to install it, with Heavy Iron as the software.
First, decided to put it a small plastic case. There are 4 mounting holes
on the PC board that accept 4-40 steel hardware. Decided to use ¼"
standoffs / spacers to lift the board off of the case as the soldering for the 60
ma current loop set screws extend well off the underside of the circuit
board. But when I tried to mount the standoffs, one was very close to the
current loop solder point, and one of the others covered one of the PC board
traces.
In retrospect, I should have used nylon screws and standoffs, but, as a
simpler solution, which works just as well, I chose to attach the PC board to
the case with 2 small pieces of velcro hook and loop.
To connect the USB cable, I bought a 12" USB converter from mini USB to
standard USB, and then used a 10" USB M/F extension cable.
Following the directions was easy. Downloaded the .INF file, right click,
and Install.
Plugged in the USBTTY USB port and Windows recognized the new hardware USB
Teletype, and proceeded to look for software. Said 'NO' to the option to
search the internet for drivers and let XP search for the drivers, which it
found and soon got a message that my new hardware had been successfully
installed and was ready to use.
So, first had to find the COM port that Windows had assigned. Start,
Control Panel, System, Hardware, Device Manager, Ports COM & LPT. Found it
listed as Teletype interface COM3.
Now to configure the interface. Start, all programs, accessories,
communications, Hyperterminal. Hyperterminal wanted a name for the connect, so I
just entered TTY. Hyperterminal then asked me for my area code and wouldn't
let me continue until I entered it. Entered the area code and took the
defaults for the bit rate, etc., and selected COM3 as the associated port.
Typed a few characters and saw the LED light on the USB TYY board flicker.
Pressed the reset button and up came the USBTTY configuration menu.
Issued the following commands:
BAUD 75 - set the baud rate
USOS - set unshift on space to match my hardware
NOTRANSLATE - since using Heavymetal,
no translation to ASCII
SAVE - saved the new configuration
SHOW - look at the configuration
As everything was working, decided to hook up the tty current loop to the
PC board. Unplugged the USB cable and, with a rather small Phillips
screwdriver, hooked up the Teletype current loop. Turned on my Teletype and
immediately got chatter from the tty as the USBTTY PC board, when not powered,
opens the current loop.
Plugged back in the USB cable and typed on HYPERTERM, but nothing was
getting through to the PC board. Closed and reopened Hyperterm with no
success. Logged off of the Windows XP user and relogged on with no success.
Stared Heavy Metal, but was unable to select COM3. At this point, realized
that COM3 was still reserved for some other program. So, had to shut down
Windows XP and reboot the system. Started Hyperterm and easily selected
COM3. Typed a couple of characters, but what was printed was not correct as no
one was translating from Baudot to ASCII.
Closed down Hyperterm and started HeavyMetal. I was running Ver 1.27 from
2006. Selected CONFIG and it immediately complained:
"failed setting word size"
"failed setting stop bits"
"failed setting baud rate"
Not just one, but a total of 9 times I had to answer OK to get past the
problem.
Typed a few characters and everything worked in both directions.
Ran the Quick Brown test and RY test and everything worked perfectly.
Also ran the UP latest news at it also printed with no problem.
So, everything is working and would highly recommend this interface board,
as it works and is very easy to configure. Going to update my Heavy
Metal program as soon as I have some time.
