Comm tables should contain additional information about the channels.
Name at the very least, for printing in RedBoot if necessary, but
the CygMon code also had some status / feature flags we might want to
adopt [didn't get included initially since there was no way to access
these data at the comm table level - it was kept in associative structures]
