- Jamie,
- You need to patch your QuickBASIC BRUN Module. The instructions on how
- to do this have been posted innumerable times on this net.
-
- A simple solution is to add the following lines before exiting the .EXE
-
- CLOSE #1 ; this is the com port you were using
- OUT &H3FC, 3 ; this is for COM 1, and MUST be the next
- ; step after close to force the modem to
- ; keep the DTR up.
-
- to use COM2 use &H2FC instead.
-
- What really happens is that the close statement will actually drop
- DTR, but the next statement will raise the DTR before the CD is lost.
