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.

Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!
This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.
But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
