$char contains a token at the point, and you can't compare that with a
hex value AFAIK.
You could use ord[1] to get the ASCII value of $char, and compare it
with the decimal value of 0xA7(167) and 0x51(81).

Tijnema,
I've tried building up a variable with ord called on each value as I
append it. When this is built I cannot find the sequence 167 81, etc
in it.
I've also tried using bin2hex on the entire buffer and checking for a7
51 to no avail.
