[Mono-list] Invalid data from CP2102 USB device

[Steve Ricketts]

I'm really too new to Linux to know what I'm talking about but could there be
some tty device parameters that are messing up the input.  I was looking at
stty and all the options there and it appears that it can change the way
input it viewed... like stripping the sign bit, assuming UTF-8 input, etc. 
I tried "stty --file /dev/ttyUSB0 -raw" thinking "raw" might not do anything
to the input but there was no change in the data read.  I'm not sure how
long those settings last... or if they have taken at all.  

Here's the output of "stty --file /dev/ttyUSB0 -a" if anyone can make sense
out of it:

linux-nsxk:~/Desktop # stty --file /dev/ttyUSB0 -a
speed 115200 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 =
<undef>; swtch = <undef>;
start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush
= ^O; min = 1; time = 0;

ff0
isig icanon -iexten -echo -echoe -echok -echonl -noflsh -xcase -tostop
-echoprt echoctl echoke

Do I read this as everything with a minus sign (-) is out and those
parameters without a minus sign are applied?

Any light you can shed on this issue is greatly appreciated, even if it's
not a specific answer.  I'm running out of ideas to chase.

Thanks,

sr
