I assume you've opened COM2 as #1 up here somewhere...

Grin. Ok, Bill. When it's "ready to end", DTR has been
slammed high on &H2F8. Which is COM2. But you've reopened
COM2. So normal housekeeping is done by QB...

Y'see, when QB ends execution of a program, she closes all
open ports FOR you (and dumps DTR on 'em). So she CLOSEs
COM2 which was opened just before your END statement,
thereby dumping DTR.

Go ahead and CLOSE it as you have... but do NOT reopen it
before the END, lest QB spite you on program termination.
You MUST close the port and slam DTR high in order to
preserve CD so you can pick it up later in whatever code
you execute next...

Make sense?
