It's caused by the 64 bit shift limit, pressing F12 causes 5 ReadKey
calls, resulting in 80 bit, but only lower 64 bit are returned:

cKbdRemote::ReadKeySequence: r=1 k=1b key1=0
cKbdRemote::ReadKeySequence: r=2 k=1b5b key1=0
cKbdRemote::ReadKeySequence: r=3 k=1b5b32 key1=0
cKbdRemote::ReadKeySequence: r=4 k=1b5b3232 key1=0
cKbdRemote::ReadKeySequence: r=5 k=5b323234 key1=1b
cKbdRemote::ReadKeySequence: r=5 k=5b323234

I've added

r++;
fprintf(stderr, "cKbdRemote::ReadKeySequence: r=%d k=%lx key1=%x\n", r,
k, key1);

after each "k |=

and

  if (k != 0) {
    fprintf(stderr, "cKbdRemote::ReadKeySequence: r=%d k=%lx\n", r, k);
  }

before "return k"

BTW: it' strange that key1 is set to 0 after
	k |=...
