[comp.sys.ibm.pc] FLUSHOT and COMMAND.COM writes, etc.

Here's a message I'm relaying from Ross Greenberg, author of that FLUSHOT
program (who doesn't have direct usenet access).

From Ross Greenberg:

"There has been some recent discussion regarding what operations set off
 FLUSHOT3 when it advises you of a write to COMMAND.COM or the other system
 files.  FLUSHOT3 intercepts and open of the COMMAND.COM file which allows
 for "write" access.  It allows you to deny that access if you so wish to. 
 Some programmers (including me)  opt to open files from time to time in
 what I'll call 'lazy' mode: open it with write access requested, even if
 you don't intend to write to the file.
 
 FLUSHOT3 is triggered by a program such as this.  Although I've not used
 FILETEST or other programs which cause this problem to occur, this is a
 pretty good guess of what's happening.  Standard caveat here: since I've
 not used the code myself, I can't guarantee that I'm not wrong.... If 
 someone would be so kind as to arrange for me to get a copy of the
 program, I can tell you exactly what is happening (thank goodness for 
 Periscope!)
 
 On the brighter side of things, I expect to be releasing the next version
 of FLUSHOT later this week [I think it was sent out a few days ago. -Lee].
 All registered users will get their copy in the mail, and it'll be posted
 to as many BBS's as possible.
 
 I'll also be shipping a copy to Keith Peterson [Hi Keith!], and he'll
 hopefully be able to post it as soon as possible.  Until I actually
 release it, I'll be keeping the name confidential:  I don't want another
 crisis like the FLUSHOT4 one. Finally, I'm working on a hardware board
 which is far more reliable than *any* software product could be.
 
 The new version is *much* better than the last, and (of course!) the CMOS
 bug has been fixed..."
