-
- A DOS program (running in a DOS box) can talk to a lurking OS/2 program
- via a named pipe. The latest version of my HOTKEY program, which I
- wrote with Peter Fitzsimmons, does exactly that. To enable hot-keys
- from DOS boxes, a small TSR is installed which watches for the hot-keys.
- When it sees one, it opens a named pipe ("\PIPE\HOTKEY" in this case),
- and writes a short message to it. That wakes up the lurking OS/2
- HOTKEY program via its named pipe server code, and it then does the
- hot-key operation (switch to the selected session).
-
- I'm new to the Internet stuff, and haven't yet bothered to figure out
- how to send files. However, if you want HOTKEY (with source for all
- except the TSR), you can get it from Bix or my BBS.
-
- The file name is HOTKEY12.ZIP (earlier versions *won't* do!).
- On Bix, it is in the IBM.OS2/LISTINGS area.
- My BBS is at 919-233-0106.
-
- I hope this helps.
