I'm not sure if this helps, but I noticed that all the letters in "@T*BFLH" are off by one, except T. In ascii, T is the only letter that is even. So minicom sems to be zeroing out the last bit of your messages, (A = ascii 0x41 -> ascii 0x40 = @ and I = ascii 0x49 -> ascii 0x48 -> I). That's the "what", but I can't think of the "why"... Have you tried other serial programs (microcom, miniterm.py etc?)
