serial gdb: interrupts were causing either overruns or stealing characters. Put splhigh() around the routines which transfer packets across the line. Since this happens when the system is halted in debug, this doesn't cause any particular problem. Now it is possible to run the link at 115,200 bps. PR: (not assigned yet, must be in limbo somewhere) Add partial support for detecting non-existent gdb devices. Add $FreeBSD$ tag. |
