Cygwin on WinXP
What version of cygwin are you using?
uname says CYGWIN_NT-5.1
cygcheck -c says 'no setup information found'
This is probably because this is a custom version of cygwin bundled with
some cross-development tools (altera nios2). It does not live in \cygwin
, and there are no packages, just binaries. I have already read on the
cross-development forum that this custom version will not co-exist
alongside a normal cygwin install, and I am wary of trying to update
pieces of it since I wont be able to use the cygwin setup util to do so.
I am trying to redirect the IO from a terminal app to a serial port.
$terminal_app > /dev/com5
Works but uses the wrong baud rate.
I am really after '$terminal_app<>/dev/com5' but this only redirects the
input. Maybe this is just not possible in the shell.
$stty /dev/com5 115200
Does not change the baud: 'unable to perform all requested operations'.
I have tried many variations on this syntax.
$stty does not even show the usb adaptor I am using on com5, but it
does not let me change the baud rate on the ports that it does see.
Did you try looking for this problem.....

That post sounds like a different problem, but I did see a post talking
about problems setting the baud.
Try a snapshot. You might be surprised.
I installed the latest version of cygwin & coreutils (5.90-1) on a
different machine - it gives the same result, 'unable to perform all
requested operations'.
I noticed that setup did not automatically choose the very lastest
versions - maybe the mirror was not up-to-date on all dependancies?.
Anyway, I had to manually select the 5.90-1 over the 5.2.1-5
At this point I am just trying to verify that what I am trying to do
should work. Does '$stty /dev/com1 19200' change the baud for anyone in
a shell or a script, or am I chasing my tail? If it works, what version
does it work for?
Should stty let me change the baud in the shell?
Where is the default baud rate I am getting established, in windows,
in cygwin, or in my usb adaptor driver?
thanks
