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.
