I am having trouble with the console.device which I hope someone
has either already solved, or perhaps the CA wizards can shed some
light on.
 
I have a little test program which opens the console.device and simply
reads one character and then writes it, thus echoing everything typed.
Just to be a good programming citizen I checked the value in io_Error
after the DoIO() call.  Whenever I type very quickly (by quickly doing
an "asdf"), the WRITE (not the READ) returns an io_Error of 1 (io_Flags
is returned 0x81 I think).  What I don't understand is why is the WRITE
failing?  If I were overruning a buffer, I would expect the READ to
return the error, not the WRITE!?!  Also, since my 1.1 Rom Kernel Manual
is "In The Mail", I can't see if it tells me what the io_Error of 1
means (the include files don't even mention errors)!  I am using 1.1
Kickstart and Workbench.
 
By the way, if I ignore the value in io_Error (as most people do), then
my program just merrily echoes along!  Somehow it bothers me to know
that the console.device is telling me something and I'm ignoring it.
