Assigning Thread Priority

[mahesh.5683]

Hai everybody,

This is my application.

* My application concentrates mainly on serial communication. Mine is a
Windows CE device application. I've used System.IO.Ports class for
that.

* For transmitting data I've created a procedure and assigned a
priority for that, using thread.priority (So that i continuously
transmit data).

* For receiving the data I use Serialport_DataReceived event. Is there
any way that i can assign my own priority level for the
Serialport_DataReceived event.

There's no simple way to adjust the Rx priority because the Port class
creates it's own internal receiver thread. If you feel you really need it
(I'd need convincing) then probably the simples way is to just use the
OpenNETCF serial classes as then you have the source and can readily modify
the priority.

Hi,

No. Why would you want to do so?

If there is a performance issue that you think this might affect (I doubt
there is anything you can do with priority that might be salutory), IMO, you
may have to look elsewhere.

While the Ports.IO class uses threading, it is via a delegate callback, for
which (AFAIK) the priority cannot be changed.
