I have an ICP server that I am communicating with using the TCPIP object. I am able to successfully connect and send commands. However, those commands will not execute until I terminate the connection with fclose.

t1 = tcpip('192.168.10.4',2008);
t1.Terminator = 'LF';
fopen(t1);
fwrite(t1,'Command goes here');
% Command still not executed on IPC server
fclose(t1); 
%Now command is executed on IPC server

Things I have tried:

I have tried setting the Terminator to every value between 0 and 127 using the following code:

for ii=0:127, t1.Terminator = ii; fwrite(t1,'Command goes here'); end

At no point does the command execute until fclose is called.

Question: What parameters should I look at changing in the tcpip object to get the remote server to execute the command I just sent? (Or what parameters should I tweak to let the server know to execute what I just sent.)
