TCP/IP connection problem

Hello all and thanks for your help,

I was trying to make an easy tcpip connection between my pc and a little board connected to my computer via USB. This one has an IP address (192.168.1.100) and a port address 21845. the simple code on matlab used is:

conn=tcpip('192.168.1.100',21845);
conn
fopen(conn);
fclose(conn);

But when I check the connection status:

TCPIP Object : TCPIP-192.168.1.100

   Communication Settings 
      RemotePort:         21845
      RemoteHost:         192.168.1.100
      Terminator:         'LF'

   Communication State 
      Status:             closed
      RecordStatus:       off

   Read/Write State  
      TransferStatus:     idle
      BytesAvailable:     0
      ValuesReceived:     0
      ValuesSent:         0

What it should appear in the status field is open, Iam rigth? Thanks for your help.

No need to answer to this question. Everything works fine now. Anyway the correct sequence is

conn=tcpip('192.168.1.100',21845);
conn %close status
fopen(conn);
conn %open status
fclose(conn);
