[TenTec] CAT control of Argonaut II

[kilcadzow]

I'm attempting to fix up CAT control on my Argonaut II. The codes go from the 
PC to the Argo, but only a bare acknowledgement is coming back.

I suspect I need to set the TX/RX identifier. The 305 serial interface points 
me to the 535/536 manual (on how to set it from the TX/RX keypad), but I 
can't find it.... The PC defaults to E0h.

Can anyone please help?

Many thanks,
