Re: CM11 Status Request (C# Language)

I've seen some unusual behavior of USB->Serial adapters compared with
actual serial ports under Linux.  I've assumed these are bugs in the
Linux drivers but Windows drivers (for some adapters at least) may exhibit
similar behavior.

E.g., a blocking read of N bytes may return after the first byte read.  So
Dave's polling ought to work, while expecting to get all N bytes with one
read may fail.
