Frage zu Telnet

[mjustin]

Zitat von DelTurbo:

Öhm, noch ne "dumme" frage hinterher. Das IndyTelnet kann das alles nicht, oder? Da müsste ich das denn auch "zufuss" machen, richtig?

Definiere "alles"

In IdTelnet.pas sehe ich einige Konstanten, die das Protokoll betreffen. Indy Telnet liefert aber keine GUI mit, daher werden Optionen wie "Window Size" in der Komponente nicht behandelt.

Es ist aber eine komplette "Verhandlung" (Negotiation) der Sitzungsparameter vorhanden, in die man sich einklinken kann.

Delphi-Quellcode:

  TNC_EOR                = $EF;   // End of Record RFC 885

                                  // by a TCP Urgent notification.
