+
+ target dbug dBUG ROM monitor for Motorola ColdFire
+ target picobug Motorola picobug monitor
+ target dink32 DINK32 ROM monitor for PowerPC
+ target m32r Renesas M32R/D ROM monitor
+ target mon2000 mon2000 ROM monitor

+
+exec-events feature in qSupported
+ The qSupported packet allows GDB to request support for exec

+ show commands can be used to display whether these features are enabled.
+
+* Extended-remote exec events
