The original 68328serial.c was intended for console operations for what I
recall. The intent of control-P and control-R handling was to
allow on console debuging of an operating module. So that the control-P
would printout debugging register information and control-R would allow
for remote rebooting of the uCsimm module. A handy feature when using the
xcopilot emulator or uCsimm for debuging applications.
For uCsimm users I see that Evan has updated the cvs.uclinux.org version
of 68328serial.c found at:
This will only enable this debugging mode for uCsimm and xcopilot consoles
when the __KERNEL_DEBUGGING__ flag is thrown at the root level Makefile.
As for uCdimm its serial driver supports multiple serial ports. I will
see if Evan and Michael Lelsie can post a patch.
