Mein Problem ist, das wenn ich über einen Telnet Client Programm ASCii Zeichen sende wie z.B. “A“ oder “B“ empfange ich diese Zeichen einwandfrei in einem remote Gerät, welches auf den befehl "A" wartet. Jetzt habe ich ein anderen Quellcode genommen der mir eigentlich zusagt jedoch sendet er die falschen Zeichenfolge.
Also es soll zum Beispiel “A“ gesendet werden bei entsprechendem Tastendruck.
Ich habe bereits die Werte in dem Code auf 65 (für A) eingegeben aber das scheint nicht richtig zu sein.
