in thread serial port hex only

Final UPDATE...the link zentara posted pointed me to

$data=$port->input;

which brings the data in and 'unpack H4, $data' works to get it in hex format. problem is solved! (though I am not sure where I am picking up 'input', but as long as it works... Thanks everyone!

[jdporter]: one prog I have has a UI which allows to input a bit mask
[jdporter]: currently it expects the bitmask to be in the form of a hex number, e.g. 0x0101
[jdporter]: but I'd like to let the user specify it as individual bits, i.e. 0b0000000100000001
[jdporter]: there is no bit/binary equivalent of hex, right?
[jdporter]: I guess that the most direct way of doing it is with some magical incantation involving unpack or whatever
