Facility Control

I am attempting to write some software to control a Ross Ultrix router over TCP using the GVG Native protocol, but I am having a bit of trouble finding additional documentation / examples of implementations of the protocol.

I have created the following command, with the goal of performing a QN,IS to query the name of the router source 132:

01 4E 30 [QN] 09 [IS] 09 [source_number] [checksum] 04

01 4E 30 51 4E 09 30 30 49 53 09 30 30 38 33 30 61 04

Upon running the command, the Router returns the following hex:

01 4e 30 45 52 09 30 31 09 51 4e 44 39 04

I've successfully implemented and tested sending a TI command, however I am not sure that my QN implementation is correct.

My questions are the following:

1.) Does my QN command appear to be malformed?

2.) If so, is my understanding incorrect?

3.) If not, how am I supposed to be receiving / decoding the source name from the router?

Any insight would be greatly appreciated.
