Create a TCP/IP client called t, using the IP address 172.28.154.231 and port 4012.

t = tcpclient("172.28.154.231",4012)

t = 

  tcpclient with properties:

              Address: '172.28.154.231'
                 Port: 4012
    NumBytesAvailable: 0

  Show all properties, functions

Write some data to the remote host and view the number of bytes available to be read in the input buffer.

write(t,1:5,"uint8")
t.NumBytesAvailable

ans =

     5

Flush both the input and output buffers.

flush(t)

View the number of bytes available to be read.

t.NumBytesAvailable

ans =

     0

The input buffer has no data.
