Thanks for the report.
Can you turn on protocol and message debuggers so that we can determine what's on the screen?

The terminal usually handles invisible fields, so it could be that there's some additional way to hide this field that will show up in the log and then we can make an improvement.

say x2c(HX3270)

Because of screen size, the output is malformed, but

• QWS3270: password field (just PA) is not displaying characters
  
• TN3270: all in one color and displays characters
  

PASSWORD has no special attributes, the solution will be somewhere else in the buffer.
