Hello everyone. I'm trying to write my own application which will control external hardware device.

So, the idea is to send a status command every 1 sec. (using timer). But except status commands I need to send another commands at any time. The worst case is when both commands will join eg. STATUS + MY COMMAND or MY COMMAND + STATUS. External hardware recognize only first part of this creture.

Just use the System.Collections.Queue[^]. Or, use this as a reference for a queue that is thread-safe (not sure if you're doing this with threads).

Cheers.

Rather than just building a string of data to send, create a queue of commands. When the timer fires, loop through the queue and send one command at a time until all commands are sent.

Using this approach also allows you to ensure that if a command exists already in the queue - and shouldn't be sent again - you can omit adding it to the queue.

Cheers.
