@Jack J Jun hi jack I was able to solve the problem yesterday I ended up using the ReadByte() method after experimenting with changing the method parameters to suit the output of my device. Thanks for your help.
Read data from a serial port that doesnt create a newline

Hi i have a device connected to a COM Port that accepts commands from my pc and sends back confirmation but doesn't create a newline leaving it open and from what i can tell because the line doesn't end the datarecievehandler doesn't even get called i have had some success using the SerialPort.Newline property and changing it to 1 or 0 which prints broken data fragments was wondering if anyone else had any ideas below is an image of what's meant to be read off com port it was gotten using tera term that picture has 3 confirmations in it which are the three 07010's but there are a couple more different codes the device can receive
Sorry if the question is a bit hard to understand am still trying to wrap my head around it myself

SerialPort.Newlineproperty? Based on my research, I suggest that you could try to use_serialPort.NewLine = Environment.NewLine;. -

2022-12-01T02:12:06.45+00:00 Thanks for the response @Jack J Jun i have tried your solution but was unable to read any data i think it still might be looking for the start of a new line but the data being read wont ever create a newline if that helps clear things up.

2022-12-08T00:49:49.017+00:00 I have talked to the manufacturer of the device and he said it it will send strings of numbers between 5 or 6 characters with no termination at all its running at 1200 baud.
