this has to do with the settings for the ports matching the settings for the
braille displays.  I'm thinking that the printer installer made some changes
to those settings.  If you look at them, you may be able to set them to
their defaults.  you can also do a system restore to see if that clears it
up.

Hello:
I have a very difficult problem that my computer technician and others can't
seem to figure all that out.  Most of the issues are related to the usage of
Jaws and the ports I have on my Desktop.



I have a Dell 1.2 GHZ computer with three serial ports and a number of USB
ports.  Up to about three weeks ago, I had been using various Braille
Display units (PB 80, PB 40, and BL M40) on COM1 without any problem.  I
have Windows XP Home edition operating system and use JFW 5 PRO.  Now all of
the Braille Display units will not work on COM1 and COM2 but will work on
COM4.  I think the problem started when I installed a new printer with an
USB cable.



We contacted Dell who assisted us through performance test and they said the
COM1 was communicating fine and dandy.  They could not help us further
because we added the two serial ports on our own.  FS said to use COM4 and
that was it.  The tech was here yesterday to try to figure out why COM1 and
COM2 do not work and still no solution.



While the tech was here, I simply pulled out an USB cable with no device on
it.  Presto, the Braille display went blank!  The tech had to power off and
on my system to get the COM4 to communicate with the display.



And even more so weird was that we tried to install USB hub into the USB
port in the back of the computer.  Windows XP would not recognize it so we
had to move the plug into the USB port in front of the CPU.  I want to point
out that we also did the performance test for all USB ports and they were
communicating fine and dandy as well.  Jaws is damn strict when it comes to
using USB ports always getting confused if we change things around on USB
ports.



Why in the heck would the new printer cause all that havoc.  We even
uninstalled the printer driver but this did not help.  Why aren't COM1 and
COM2 working with Braille displays????



Thank you!
