Subject: Re: [RTTY] 4-port serial card for Windows 8.1 results
I have been looking at this thread and I know I had purchased a
Serial
Adapter
cable that went from USB 2.0 to two male serial connections.
It was recommended to me that it does work well,
I cannot confirm because I have not tried it yet. I have not had
a need to
use it,
plus my mother board does have a serial header. I purchased for
possible
future needs.
It is a Micro Connections product. Purchased on Amazon
On the package it says the CD includes drivers for Win7 - Win
8 - Vista - XP
and Mac
Here is a link:

I just thought it was easier than installing a board. Just
another thought
or possibility.

Joe,
Thank you very much for this information. I did not realize 8.1
had this
capability.
Thank You!

Part of the problem with installing drivers in Windows 8/8.1
is the
new hybrid sleep (fast boot) capability. In essence, Win
8/8.1 closes
any running applications then saves the operating system and
hardware
drivers image to disk just like hibernate. When rebooting
that old
image is reloaded complete with all the drivers that were
previously
installed - even if the hardware changed. If the previous
image had
drivers for hardware that was no longer present or drivers
that were
to be replaced, that conflict can cause page faults and other
(BSOD)
errors.
When installing new hardware the best thing one can do is to
hold the
shift key while shutting down Windows 8/8.1 before making any
hardware
change, install any new drivers, then restart Windows 8/8.1
before
trying to run anything new. Shift-shutdown and restart both
force a
complete (fresh) reload of the operating system and all
drivers.
Another little known tip ... when installing new USB devices,
always
disconnect any previously connected devices and restart before
connecting a new USB device for the first time. This allows
drivers
for the new device to be installed with a "clean slate" and
prevents
older drivers and drivers from hardware no longer present from
interfering with the installation of a new device.

Thanks to everyone who sent information on the serial cards
they were
using in their Windows 8 computers. I purchased a new Dell
3847 desktop PC with Windows 8.1 and it arrived this past
Monday.
On the serial card, I decided to go with a suggestion from
Joe, W4TV,
on the Syba model SD-PEX15011 for three reasons. One is that
Joe is
usually good about suggesting hardware (I purchased two USB
sound
cards he recommended and they work great), secondly because
this
particular 4-port board is the sister of the 4-port board I
have been
using in my XP Pro machine for many years, and thirdly
because of the
price. It is cheaper than any of the others. Although the
manufacturer is listed as Syba, it says "Best Connectivity"
on the box.
I purchased the SD-PEX15011 from Newegg on Monday and it
arrived today.

I installed the board this evening using the instructions
that came
with the board. I'm sorry to report that nothing worked as it
was
suppose to but in the end, for reasons I can't explain, all
four
ports magically started working.
The instructions said to install the board, turn on the
computer and
Windows would recognize it - it did not. Windows did not like
the
board being installed and kept giving an error that it had to
shut
down and restart because "page fault in non-paged area".
I decided to remove the board and install the driver on the
disk that
came with the board, then re-install the board. There were
Windows 8
drivers on the disk. Windows still did not like the board
being
installed. On occasion it would give me the "page fault"
error and restart, but I did notice that COM 1 was showing up
and the
other ports were also showing in Device Manager but Windows
didn't
know what they were. I tried re-installing the driver but it
wasn't
working. I went online to find updated drivers. The drivers
on the
Syba website were actually older than the ones on the disk
and I
didn't see any for Windows 8. I did find a set of
instructions for
Windows 7 that suggested to "Disable Driver Signature
Enforcement". I
finally found instructions on how to do this in Windows 8.1
because
the instructions for "Disable Driver Signature Enforcement"
on
Windows 8 are totally different. I am finding out that
Windows 8.1 is
different than Window 8 in many ways.
Rebooting after "Disable Driver Signature Enforcement" helped
keep
the PC from wanting to restart. I re-installed the drivers as
Administrator but the ports did not show up in Device
Manager. So I
switched over to my non-Administrator account for no good
reason
other than to check the Device Manager; lo and behold, all
four ports
showed up in Device Manager.
I went ahead and tested all four ports and they all work for
radio
control and FSK/PTT. I restarted the computer several times
and have
not gotten the "page fault in non-paged area" error and
everything
seems very stable.
I don't know if I would recommend this board to anyone other
than to
someone who has time to play with it to get it to work. I
think it's
going to be OK, but if you want to spend a little more money,
maybe
something like a StarTech would install better. I don't know.
I will give it the smoke test in SPDX RTTY this weekend. I'm
just not
a fan of USB-to-serial adapters for FSK. Especially with the
BARTG 75
coming up on Sunday. Definitely need a legacy COM port for 75
baud on
a homebrew transistor FSK interface!
