Problema Multi Thread y Server Socket Borland C++ 6

Hola, estoy comunicando dos aplicaciones por medio de Socket, tengo un ServerSocket en C++ (Borland 6) que por cada conexión recibe un mensaje desde un Cliente Socket en Foxpro 6, mi problema es que no he logrado comunicar FoxPro con C++, alguna idea?
Dejo los códigos:

Cliente Socket FoxPro 6
Código:
ThisForm.tcpClient.Object.RemoteHost = "172.16.24.128"
ThisForm.tcpClient.Object.RemotePort = 23

IF ThisForm.tcpClient.Object.State = 0
		*WAIT WINDOW "Socket State 0: Cerrado!" TIMEOUT 1
		ThisForm.tcpClient.Object.Connect()
			IF ThisForm.tcpClient.Object.State = 7
				WAIT WINDOW "Socket State 7: RE-Conectado OK" TIMEOUT 1
			ENDIF						
	ENDIF
	IF ThisForm.tcpClient.Object.State = 6
		WAIT WINDOW "Socket State 6: Conectando..." TIMEOUT 1	
	ENDIF
	IF ThisForm.tcpClient.Object.State = 7
		*WAIT WINDOW "Socket State 7: Conectado OK" TIMEOUT 1
		ThisForm.tcpClient.Object.SendData(This.Value)		
		WAIT WINDOW "Mensaje Enviado OK" TIMEOUT 1		
		*ThisForm.tcpClient.Object.Close() 	
	ENDIF
	IF ThisForm.tcpClient.Object.State = 9
		WAIT WINDOW "Socket State 9: Error" TIMEOUT 1

Tu programa en C se queda escuchando en el puerto?, probaste hacerle un telnet al puerto en donde escucha tu proceso y se pudo conectar?, yo comenzaria a descartar por ahi y luego pasaria al proceso cliente.
