B4R Question Flushing or handling serial incoming chars

[tigrot]

Hi everybody
I'd like to flush incoming bytes from serial port. I have a long running task and incoming bytes will queue on their ports. Is it possible to check the incoming stream or to clear it while executing sub?

Thank you!

The NewData event is raised whenever there is data available. You can ignore the data when you first connect.

Hi Erel
Since I'm in a loop, is the execution interrupted and event served? According to my tests this doesn't happen till I return from the sub.
I need to trasfer log files from internal SD to an USB memory. The copy is quite long and I need to go on with housekeeping.
I'll do the copy in an timer, so every block is copied and between blocks' copy there is time to handle the incoming streams.

No.

You can probably use CallSubPlus here. It allows you to run a sub after the set interval.

Thank you. I have a question: CallSubPlus returns to the statement following the call?

No.
