-ui option

For Linux with X window server support, starts dbmlsync in shell mode if a usable display isn't available.

Syntax
mlsrv11 -c "connection-string" -ui ...
Remarks

When this option is used, dbmlsync tries to start with X Windows. If this fails, it starts in shell mode.

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 shell mode.
