Communicating with an 86412B via VXI-11

I need to connect to an 86412B OSA over ethernet (VXI-11).  I have a Python based VXI-11 library (https://github.com/alexforencich/python-vxi11) that works perfectly with other Agilent/HP devices (MSO7000, DSA90000, E2050A, E8361C, 8164B).  However, there seems to be an issue with communicating with the 86412B OSA.  I am attempting to connect with the resource string "TCPIP::xxx.xxx.xxx.xxx::hpib7,27::INSTR" where 27 is the GPIB address of the unit.  I can successfully connect and send commands to the OSA, such as "*RST".  The OSA goes in to remote mode and the commands do take effect.  However, I cannot read anything off of the analyzer - it always times out.  Any ideas on what might be going on here?
