[TenTec] Paragon II Computer Interface Problems

I am trying to use the II's computer interface. I am having difficulty
with the responses to queried data, but not to receiving CDE (Matrix) data.
TRX-Manager indicates communication error using IC735 emulation and XMLog complains
about missing EOMs for IC735 and Paragon II modes. TRX-Manager works well when
the II is put in CDE (Matrix Mode), but does not succeed when it asks for replies
except for operations setting the transceiver.

The information returned seems to be correct, but possibly in the wrong format
(at least according to my Paragon II's manual) One Debug program that I have
used shows an additional byte in the mode/filter response and in the frequency response.
I don't have the source for the debugger, so it may be manipulating the data before 
presentation.

The manual I have indicates that byte 5 should be the first byte of the response data.
But in the debugging printout, byte 5 appears to be the command sent to the transceiver,
i.e. 03H for query frequency and 04H for get mode.  In addition, the get frequency seems 
to have an extra byte in the frequency after the MHz byte and just before the FDH byte.

Can those with a manual verify how many data bytes should be received for 03 and 04 
queries?  Could be I have an early version of the manual or the controller code.  Is
there a version number on your receiver ROM?

Thanks,
Ed, N5EI
