[Oberon] AosTCPServices on WinAos

[Dan Parnete]

Hello Felix,

I'm new in area, and I'm discovering the wonderful world of Oberon. I 
like it so much, that I intend to switch here all me future projects. I 
should like to write some server code running on both Aos and WinAos. 
I'm trying to run this on WinAos (it runs fine on Aos) but it fails on 
AosTCPServices.OpenService:

MODULE DpsServer;

IMPORT AosModules,  AosOut, AosTCP, AosTCPServices, AosIO;

CONST
    port = 17;

TYPE
    ClientAgent = OBJECT (AosTCPServices.Agent)
    VAR w: AosIO.Writer;
    BEGIN {ACTIVE}
        AosIO.OpenWriter( w, client.Send );
        AosIO.WriteString( w, "I'am ready!" );
        w.Update;
        Terminate
    END ClientAgent;
   
VAR
    service: AosTCPServices.Service;

PROCEDURE Open*( par: PTR) : PTR;
BEGIN
    RETURN NIL
END Open;

PROCEDURE Close*( par: PTR ) : PTR;
BEGIN
    Finalize;
    RETURN NIL
END Close;

PROCEDURE Initialize;
BEGIN
    AosOut.String( "DpsServer: " );
    AosTCPServices.OpenService( service, port, NewClientAgent );
    IF (service # NIL) THEN
        AosOut.String( "service started." );
    ELSE
        AosOut.String( "service failed to start." );
    END;
    AosOut.Ln;
END Initialize;

PROCEDURE Finalize;
BEGIN
    AosTCPServices.CloseService( service );
    AosOut.String( "DpsServer: service stoped." ); AosOut.Ln
END Finalize;

PROCEDURE NewClientAgent( c: AosTCP.Connection; s: 
AosTCPServices.Service ): AosTCPServices.Agent;
VAR a: ClientAgent;
BEGIN
    NEW( a, c, s );
    RETURN a
END NewClientAgent;

BEGIN
    Initialize;
    AosModules.InstallTermHandler( Finalize )
END DpsServer.

Aos.Call DpsServer.Open
System.Free DpsServer ~




TRAP access violation in thread Service

AosWinsock.Accept  PC = 4929
    C =  02D7E5E0H AosWinsock.Connection
    newC = NIL reference ( 00000084H )
    res = 0
    ret = 0
AosTCP.Connection.Accept  PC = 1208
    @SELF =  02D7E550H AosTCP.Connection
    client =  00000000H (AosTCP.Connection)
    res = 0
    resi = 0
AosTCPServices.Service.$$  PC = 54
    @SELF =  02D7E4F0H AosTCPServices.Service
Unknown EIP = 02D7F21AH EBP = 0361FF88H


Is it anything I'm doing wrong ? WinAos needs any special setting for 
running AosTCPServices ?

Thanks,
