TCPIP instrument communication

I've been working with a LeCroy scope (Waverunner LT372) but I've had a bit of trouble communicating with it via ethernet. I thought the tcpip command worked similar to the gpib. I'm definitely establishing some sort of communication, and I seem to be able to send commands to the instrument, but most don't execute, and I definitely can't get the scope to return queries I send to it. My instrument establishment communication is as follows:

tobj = tcpip('IP address of instrument', 'port of instrument'), where both the port and IP address are set on the instrument fopen(tobj)

Then I use the typical fprintf and fscanf to send/receive information from the scope. Any thoughts? Thanks

Could you check

get(tobj,'Terminator')

As best I can guess from the Waverunner documentation, this should probably be LF.
