A silly question, is the destination address in a UI frame
From the AX.25 2.2 spec, section 2.2.13, Address-Field Encoding:

should be made up of /upper-case alpha/ and numeric ASCII characters only."
Yes, I had read the spec. My question was one of, does the software

Linux AX.25 stack's case, it feeds it all through `toupper`, which
basically will clear that extra bit (0x61 becomes 0x41).
