Alan, Sorry for this late answer! Thank you very much for your help. The problem was indeed with the MTU DISCOVERY option. Is now disable and TELNET and FTP are working fine. As you guessed on your first message, MPX-32 is an old operating system (75's vintage) but it was widely used for 15 years as a real-time operating system on flight simulators and that's why I have to continue dealing with it :-\ !!! Anyway, thanks one more time and take care!
