I cannot seem to find what is wrong with my field request string for Level1Fields under protocol 5.2. I know there is something I am missing but I can't find it. Can you please verify that this request string includes valid fields?

Many Thanks!

It looks like the /r/n is missing off the end of the string.

I was trying to save you having to read a few lines. Attached contains the setDefaultFieldsProtocol5_1 method (which works) and the setDefaultFieldsProtocol5_2 method which does not work.

Does a flush at the front help? There could be something left on the buffer I suppose. If not, just sending this message should be fine and it does seem to work for me on this end. Can you try to enable all L1 logging in the IQ Diagnostics app and send me the resulting IQConnectLog.txt file from your Docs\DTN\IQFeed directory? Maybe there will be some clues there that can help me.

Tim,

Your check enabled me to find an upstream switch statement that I did not have falling-through properly.

Many Thanks!
