Issue:
When viewing the map layout in the MAPC layout screen (option 4), the map becomes corrupted.
All of the fields are condensed (scrunched) towards the top left corner of the screen.
Environment:
CA IDMS all supported releases.
Cause:
This can occur when running through a terminal emulator such as supersession or SIM3278.
The emulators act as if they do not support the READBUFFER command.
The layout screen in MAPC requires a full buffer read otherwise this corruption will occur.
Resolution:
Enable optional bit 44 in RHDCOPTF.
