Finally have successfully opened a window, and can output to it. (using
DoIO). When I change IOStdReq.command to CMD_READ, with length of 1, and
io_DATA = &c (c is defined as char), that task locks up and refuses to do
anything (other tasks run fine). Am I missing something? Thought command,
Length and Data were the only fields I had to change in order to input
something.
