RE: [ECOS] How to handle serial port input?

["Tom Vandeplas" <tom dot vandeplas at 4g-radio dot com>]

Ok this works great, thx for the input.

I have one additional question:
I would like to use a larger block size (len parameter) for performance
reasons. If I do so, is it possible to set a time-out on the thread.
If for a given time no input is generated on the serial port, how do I know
when to flush it.

One possibility is to configure the device to non-blocking and let it read
the data that is available, but this isn't as nice as the blocking version.
Or is this the only possible solution?

Just launch the thread and let it read from the device. It will sleep
until there is data to be read.
