Serial data missed/skipped

[DaAwesomeP]

Hello,

I'm unsure how to make this repeatable for others without a similar hardware device, but I am experiencing a lot of data loss.

I have a USB serial device that writes out a bytecode. I am reading with await aioserial_instance.read_async(size=1). Every once in a while (maybe when it switches between async tasks), the next read byte has skipped forward quite a bit in the buffer. This is at a really high baudrate (230400).
