If /S FTPD is issued while FTPD is already running, a second instance starts. Both bind to the same port (the second closes the first's socket as "stale"), both respond to MODIFY commands (double WTO output).
Need to detect an already-running instance at startup and abort with a message.
Options
- MVS Name Token (IEANTRT)
- ENQ on a resource name
- Check if port is already bound and refuse to start
