I do not know what is meant by SYMATRAX TELNET, but I will try to help out. Normally you would do TELNET AS400. This would try to start a session to the AS400 with a name of QPADEV…. Now the AS400 you want to start a telnet session on should have a Subsystem active that allocates the QPADEV… workstation. If so it will display the Signon screen for that subsystem.
