I have to question your description of "hangs the server".  From another
machine, can you ping or telnet to the "hung" server?

I have a vague guess: that this Cobol app is actually compiled for
OpenServer, and that it's using an ioctl which UW7 understands as a
console video mode change (on OSR5 it's a tty mode ioctl).  If I'm
right, you should be able to run the app under `scompat`.  Try that.  If
it helps, please reply -- I only learned about `scompat` recently and
this would be my first live test of using it...

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
