Remote debuging

I’m trying to debug remotly an application using the Watcom debuger via
TCP/IP. When i start tcpserv on the remote host i have a
SIGSEGV at 0005:000056D7
The same probleme occurs on the host where WD is installed when i move
tcpserv from its original path to another path and try to start it.
Is there others files i’ve to put on the remote host ?

Thanks for your answers.
