* pcem v2 lockup after file copy: The 'good' trace does a DOS_FILETIME to get
 the file stamp, followed by a DOS_READ. The 'bad' trace does a DOS_FILETIME
 but doesn't seem to get as far as the DOS_READ; it either does a DOS_CLOSE 
 or just hangs straight away.

* Rewrite server with knowledge gained from developing client. In particular,
 CWD stuff can be dumped since all paths should be absolute.

* Try and llmonitor Loco2 against PCW server.
* Test client against live servers!

! Have had to monkey with the laplink cable bit assignment again, so need
  to recheck with physical hardware.

* Check the test client can connect to a real PCW and transmit / receive 
 packets.




* Allow v1 server access through PCW serial port?
