Just FYI: there don't appear to be any obvious loops in which SerClose could
hang. There are no loops *in* SerClose, one call to SysLibTblEntry (no loops),
two to MemPtrFree (wouldn't expect this to hang unless the heap were corrupted,
which shouldn't happen when Poser's watching it as closely as it does), and one
to SysSemaphoreDelete (no obvious loops, but who can tell for sure with that
source code...). If SerClose is hanging, it's for some totally untrivial
reason.

Could you send a little code, this doesn't seem to be a problem with an
obvious solution.
