Hey,

As per my understanding, read(t,1) gives the following error.

Error receiving data from the remote server.

Additional Information: Operation timed out before requested data was received.

read(t,count) reads the number of values specified by count sent to the TCP/IP server t from the client connected to it. You are reading value from the client which is causing the error.

Try using:

read(server,server.NumBytesAvailable) 

You can see the documentation and examples provided at

Additionally, you can read from the client when you read data from remote host over TCP/IP. Check this out for more information:
