From GSPSupport.pm (frame2packet): 

    for my $byte ( @frame ) {
        my $lowbyte  = ( $byte & 0x0f ) + 65;
        my $highbyte = ( $byte >> 4 ) + 65;

I tested this subroutine with numbers ranging from 0 to 9,999,999,999 and I can tell you two things.

1) $lowbyte is not a byte, it only has four bits. It is a nibble.

2) $highbyte is not a byte as it can contain any value above 255 (0xFF).
