Hello,
I noticed that there is an omission in the A12 manual, in the section regarding serial settings beginning on p. 42
In the explanation of COM1 Mode, discussion of mode 6 (CAT to COM2) is omitted.
It is included in the online RRC configuration web page.
Also, perhaps it would be helpful to include an example setup of COM1 mode 6 use somewhere.
Thanks for a wonderful product and support to match,
