In most cases such as this the attribute of the filed is set to do the enter at the end of the scan.. since this is not the case you can try setting the emulation parameter "Auto Send Screen"
if this does not get the desired effect you would then want to script this behavior with in the script editor to send when the cursor reaches a certain position..
Unfortunately it not work, and the position of cursor can be different.
Can't the Telnet recognize an unprotected high intensity field?
the telnet client will behave anyway that the server would like it to respond however the server is the one that has to determine that behavior.. for example if a field is cap locked by the server the client will type in all caps.. if the server has an enter at the end of the field that will also be executed.
We have the scripting to help over come these issues and can be tailored in just about any way possible. What i suggest is to write out all the requirements for the fields in question.. Once the outline is completed you can then begin to script the behavior you want.. the idea of the cursor position was based on the comment in the original post, "Complete filled". i took that as the field was completely filled.. however you can use the script editor to work the behavior you are looking.. it may also need the use of the screen reformatter as well to accomplish the goals you are looking for,,
