Unable to Receive data from Cobas e411 Serial Port
-
Hi, I am new to this platform also new to C# code. I want to communicate with my Cobas e411 machine and receive data in text box but no data being received. here is my code what i used. Kindly help Kindly share the code for receiving the data from machine. I tried but its not working. No Data being received. My code is below.

Start at the beginning: use HyperTerminal or similar to check that the PC can "see" the device, and that data is being received and is at least slightly comprehensible. If it isn't, then you need to fix that first! When it is, then move on to code - and use the debugger to find out if the events are firing correctly - I'd add an SerialPort.ErrorReceived Event (System.IO.Ports) | Microsoft Learn[^] handler as well, in case the data format isn't what you think it is.

I don't know this Device ... but when we speak about serial communication we have normally a Handshake between the Application and the Device. So I suggest that you carefully read the Documantation of this Devide and try to find out how to communicate with it. I don't believe that it is sending Bytes without an request to do it ...

In general that question is surprisingly popular on this site. Having been asked multiple times over the years. General answer to all of those is to find the specification for the device and then implement it.

Presumably you are not new to programming and are at least mid-level programmer in some other programming language. So 3-5 years of professional experience. Otherwise this is going to be a very difficult task for you. It would be a non-trivial task for me and I have many years of experience and have interfaced with multiple devices including serial port devices in the past. Steps 1. Learn about serial programming in general 2. Find the protocol/communication specification. You MUST have this. Be careful if googling since I came across at least one site that seemed sketchy. But since you presumably have the actual machine maybe you have a business account that will provide it. 3. Study the specification. Read it end to end. Don't skim. 4. Find some examples in C# for serial communication. NOT for this device. But rather just how to use serial ports. Maybe find several. 5. With all of the above you can probably start laying out a solution to your actual problem.

Thank you brother. I ll try and then will revert.

I'd attempt explicit reads and track "bytes read" before depending on the (flaky, IMO) received event.
