2 com port parallely

[Ranjeet_Singh]

I am working on a application in which I may need to read value from one com port and need to write the value to other com port and vice versa. During testing I will be doing this lots of time....It might possible that after reading data from one com port and after few proceesing I need to write to other ports and vice versa.

Is using two parallel while loop is good approach?

Hi Ranjeet,

as an active participant in the forum you should know that it is considered rude to bump threads within 2 hours…

Well yes, I would use separate loops to handle the COM ports.

I know..It was by mistake..My monitor was off

I also thought so ,but managing the data will be difficult.. you see I need to read data from one com port and write to other com port.

Hi Ranjeet,

you surely heard the words ActionEngine, FGV, queue, notifier, KeyValuePairs, (and several more) before…

Who said it would be easy? 😄

[Ranjeet_Singh]

Yes few of them......What is ActionEngine and KeyValuePairs?

Any link will be great !!!!

Personally, I would 4 loops here.

1) Read COM1

2) Read COM2

3) Send COM1

4) Send COM2

So you have two loops just for reading the serial ports.  They should use a queue to send the data to whoever needs to process it.  You have another two loops just for sending data that needs to be sent.  They get the data to send via queues.  This is a version of the Producer/Consumer.
