Additionally, what kind of buffers does your device have? I'm using
pyserial to control a very "sensitive" device with nuttily
implemented buffering strategy. It has a "fast" and a "slow" buffer
which are filled in order, and no signalling to the outside sender
on how full they are. If the fast buffer fills the slow buffer
kicks in and requires less transmission rate. That may be how
characters could be lost with you.
