For Linux with X window server support, starts dbmlsync in console mode if a usable display isn't available.
mlsrv10 -c "connection-string" -ui ...
When this option is used, dbmlsync will start whether or not the X window server starts. First, dbmlsync will try to start with X Windows. If this fails, it will start with a console UI.
When -ui is specified, dbmlsync attempts to find a usable display. If it cannot find one, for example because the X window server isn't running, then dbmlsync starts in console mode.
