Debugger can't find active sessions
Not sure it can help, but my situtation is as follow :
I use linux Ubuntu at home and Windows 7 (enterprise) ar work.
On linux I've never had any connection problem between openmsx and debugger. On Linux the debugger (or openmsx?) create a temp file holding the process id of the connection, unlike Windows which create a TCP connection with an assigned port.
On Windows, if you execute the command "netstat -an > nstat1.txt" before establishing connection and "netstat -an > nstat2.txt" once connection estalished, you will get the TCP lines connection with port number.
(by comparison between the two files)
For instance :
1) before connection :
TCP 127.0.0.1:58494 127.0.0.1:9962 TIME_WAIT (this is openmsx waiting)
2) during connection :
TCP 127.0.0.1:9962 127.0.0.1:58494 ESTABLISHED (debugger)
TCP 127.0.0.1:58494 127.0.0.1:9962 ESTABLISHED (openmsx)
A few months ago, I developped a program (C language then Java) to communicate with openmsx. On Ubuntu, no problem, but on Windows the connection has always been refused. I therefore wonder if Windows (depending on the version) allows TCP communication between applications only under certain authorization conditions
