Hi,
I have a problem when trying to perform a Read over a socket from an LPT3000R Spectrum Analyzer.
Whenever I perform a read, the above IO Error is thrown and I lose my connection. To ensure that I was not doing anything wrong, I tried using the SimpleReadWrite sample from the .NET 4.0 Examples. The sample code also throws an error upon read. I'm using a C# program in VS2010. My platform is Win 7 64 bit.
Any insight would be appreciated.
Below is my capture from NISpy:
