I'm hesitant, as we do not currently depend on awk

[port19x]

Yeah, no new dependencies

If we gonna rely on external application for hex2ascii we would go with xxd rather than awk, as it's literally a few words xxd -r -p, xxd comes with vim so it's available in nearly every distro, but since we are not in new dependencies by using our brain as much as possible to tackle the problem with logic.
