Yes, the TDK Debugger uses a different Tcl-oriented protocol as it 
preceded dbgp and was designed just for Tcl.  The debugger backends 
between TDK and Komodo use the same debugging core for Tcl though. 
There handling of spawnpoints will vary as the protocol allows, but as 
it is the debugging core with the support, it should be "the same".

In my testing, one obvious variation that I noted was that TDK will 
report invalid spawnpoint lines (lines not recognized by the debugger as 
allowable spawn points).  In TDK, a dialog will show to indicate this, 
but I received no such feedback from Komodo.

Currently only [exec], [spawn] and [thread::create] are recognized spawn 
point generators.  This is a hardcoded core list (unless you extend with 
.pdx files), and I noticed one quirk about this ... exp_spawn was not 
recognized, whereas spawn was.  This is something we need to correct.

In any case, that may be what you hit.  You are using the correct dbgp 
commands though.  Can you describe in more detail the tests you are 
using?  Have you tried running dbgp_tcldebug with -log (activate 
logging) and -logfile myfile.txt (redirect log from stdout to file)? 
That should provide more detailed information.

Regards,

Jeff
