The apple2enh target supports a PFS that requires much less RAM than the POSIX
file system. However this benefit comes with the following restrictions:
- Only one file may be open at the same time.
- Only read operations are supported but no write operations.
- The files must be located in the same directory the application is located in
(the ProDOS prefix may very well point to another directory).
- The network MTU size must be set at least to 1265 (the default is 1500).
- No network function may be called while a file is open.
