   Friday I'll posting a new verion of PMFS to accomodate slower baud rates
   and configurable built-in cache in the driver.   The driver cache can be
   anywhere from 0 slots (blocks) to as many as you have memory for.   The
   cache only caches Single Block I/O because 90% of these are you directory
   and FAT read/writes.   Just cacheing those is a great speed-up.
   The cache is configured during the first installation of the driver.
   Either type pmfs {blocks} from a CLI or rename pmfs.prg to pmfs.ttp and
   pass the number of blocks in the dialog box.
   I'll still looking for a way to emulate ? the GEM [ESC] key function.
   Is this clearing TOS's cached directory blocks or something ?   Where
   do I find them to clear them myself ?
