| 12 | + | - Put **tlntsend** in your Implementation/Uses clause | |
| 13 | + | - You will be using the QOTD port \#17 | |
| 14 | + | ||
| 15 | + | ``` pascal | |
| 16 | + | procedure DisplayQOTD; | |
| 17 | + | Var | |
| 18 | + | MyClient:TTelnetSend; | |
| 19 | + | szQuote:String; | |
| 20 | + | ||
| 21 | + | begin | |
| 22 | + | MyClient := TTelNetSend.Create; | |
| 23 | + | With MyClient do | |
| 24 | + | begin | |
| 25 | + | TargetPort := '17'; | |
| 26 | + | Timeout:=3000; | |
| 27 | + | TargetHost := 'alpha.mike-r.com'; | |
| 28 | + | end; | |
| 29 | + | If MyClient.Login then | |
| 30 | + | begin | |
| 31 | + | szQuote := MyClient.RecvString; | |
| 32 | + | If szQuote = '' then | |
| 33 | + | begin | |
| 34 | + | MyClient.Send(LineEnding + LineEnding); | |
| 35 | + | szQuote := MyClient.RecvString; | |
| 36 | + | end; | |
| 37 | + | end | |
| 38 | + | else szQuote:='Could not retrieve quote'; | |
| 39 | + | ||
| 40 | + | MyClient.Logout; | |
| 41 | + | ShowMessage(szQuote); | |
| 42 | + | FreeAndNil(MyClient.); | |
| 43 | + | end; | |
