Hello,

I'm transitioning my instrument communication from tcpip to tcpclient. Most stuff I had no problems with, just changed how the object is created, but one device I'm having trouble with. I have a ZYBO Z7 eval board.

Previously, I was connecting to it using the following:

ZYBO = tcpip('192.168.178.100', 33)
fopen(ZYBO)

then I would query, for example:

query(ZYBO, 'DMA_STATUS', '%s\r\n')

and it would return:

ans =
'Ready'

Now I'm connecting to it by using

ZYBO = tcpclient("192.168.178.100", 33, "Timeout", 5);

then sending either the same query or

writeread(ZYBO, 'DMA_STATUS')

and I'm always getting an answer in the form of the same command, i.e.:

ans =
    'DMA_STATUS'

I'm not hugely familier with tcpip communication protocols, I don't even know why I had to add %s\r\n in the previous version, but at least it worked. What am I missing now?
