Re: AS400 telnet traffic

["Martin A. Rubio" <mrubio () securetech com co>]

Hi,

Use EBCDIC ..... In ethereal, for example, select a packet of the telnet 
transmission and right-click on it, selecting "Follow TCP Stream ...", 
then select EBCDIC from the bottom to see plain characters of the telnet 
session .....

Regards,

Martin
