Hello, With brltty4.4, sometimes, when there is heavy traffic over the serial line, gioAwaitInput will claim that there is no input available. It then says input is available after more info is received from the device. It seems that some buffer isn't getting flushed properly. For a long time I was suffering from what seemed to be lost packets(not dropped, but truly missing). I then realised, that these packets were coming through as soon as a new packet was sent from the device. Flushing on the devices end did not have an effect, but it is possible that Arduino is malfunctioning as the Arduino serial libs are notoriously buggy... I solved the issue by having my device send a ping every 50ms. This ensures that those previously missing packets get pushed through by the ping.
Any clue if this could be on BRLTTY's end? Tim
