Running the PCS batch file to start the IBM 3270 emulation program
will hang the system. It appears to load the program but does not
return to the command prompt and locks up the system.
When IBM PCS version 1.0, 1.21, or 3.0 is spawned with EMM386.EXE
loaded with NOEMS or RAM switch in CONFIG.SYS, it will hang the
system. The system will need a hard boot.
Excluding C000-CFFF with EMM386.EXE will solve the problem. For
