You can create a macro to signon. When you are at the signon screen, click on the start macro, go through the steps of signing on the green screen. Once you have signed on, click on stop macro. Then you can go to Edit, Preferences, Macro/Script, select the Macro you created and click on OK. Each time you sign on to the green screen it will automatically put in the user name and password. If it is the first time you are opening that session, you will still be asked for the initial password but once you put it in, the green screen will auto sign on.
Hope this helps,
To avoid the Windows signon, don't use an emulator that issues signon requests to the Signon server (or TN5250E), e.g., don't use the iSeries Access emulator -- use Mochasoft for example. To avoid the green-screen signon, use an emulator that signs on through the Signon server but set the session to 'Bypass signon', e.g., use iSeries Access emulation with 'Bypass signon' checked.
Usually, 'Bypass signon' <b>should</b> be done. Signons should not be done through the green-screen signon panel since the characters for a display panel are sent in clear-text across the network. Use the Signon server function with 'Bypass signon' to eliminate typing password characters into a display. System value QRMTSIGN should be set to *VERIFY.
Some information may be seen in [help] for the STRTCPTELN or TELNET RMTPWDENC() parameter. This command supports TN5250E.
