Scott, I determine the transmission is complete by the arrival of a trailer record. Guessing from the rest of your reply and the situation, what I do next is incorrect, which is varying off the line, etc. How would I detect their EOT (I'm thinking by detecting a return code), and particularly how would I acknowledge it? Haven't tried running comm. trace. Appreciate your help.
It sounds like you are trying to do what we do, so I'll add my 2 cents worth (particularly because it was difficult for me to learn this stuff!) There is info on some of this in the archives; that's where I got the basis for my program.
In our case, we have to upload some records to identify ourselves, then we download the file based on that. After I upload the identification, I write a blank record with ALWWRT set (*IN31). My comment in the program says it's EOT.
Then I read from their file until I get RCVTRNRND (*IN90) then I close the file. Maybe they want you to send ALWWRT again, though.
