Thank respected Larry Miller.

I shall use Microsoft Winsock Controls, version 6.0 in Visual FoxPro 6.0.
I launch the appendix SERVER.
I Establish further:
.Protocol = 0 && TCP
.LocalPort = 1001
.Listen() && I establish to listen
I launch the appendix CLIENT.
.RemoteHost = "10.15.6.53"
.RemotePort = 1001
ON the client I bring on CONNECT - the answer .T.
Further does not work SendData.

P.S. 1. In Delphi the Microsoft Winsock Controls works.
2. Excuse for poor English.
