I've seen similar problems where some point along the path fumbles max-MTU sized packets.
You can test this by setting the MTU on the PC initiating the TSO session to something smaller, try 1200, it's usually just a small amount smaller size MTU that works. 3270 screen sessions will work as long as they don't try to send a max MTU frame, but IND$FILE will almost guarantee a max MTU frame.

It runs over the 3270 data stream (the 3270 emulation session). So long as you can access TSO with no problems, then IND$FILE should work OK. How are you invoking IND$FILE? In the past, I would get out of ISPF, back to the TSO ready. I then switched to a command prompt and used the "send" or "receive" (IIRC) commands, which were a part of the 3270 emulation software package. One thing that I know of which will hang up an IND$FILE will be an asynchronous message coming to the TSO user, such as from a NOTIFY on a job or someone using the TSO SEND command to send a message. I always used a PROFILE NOINTERCOM to help avoid this problem. > > Regards, > Scott > > -- The unfacts, did we have them, are too imprecisely few to warrant our certitude.
