Cant read socket registers from socket0

Sending the following commands (represented as hexadicimal messages) after confirming the W6100 is indeed visible on the network via commands as mentioned in the datasheet on page 83.

0x000,0x0D,0x02 //Setting the socket0 mode register to UDP4

0x0114,0x0D,0x15 //Setting the socket0 port to 5000
0x0115,0x0D,0x88

0x0010, 0x0D, 0x01 //opening the socket0

Whenever i read adress 0x000 the device return nicely 0x02

Whenever i try to read the adresses 0x114 i get no data eventhough i written my bytes into the adresses.

Does anyone know why?
