The messages are sent to stderr.  Possible solutions are in the FAQ
(faq100.zip): 
1) You can put ``2r1'' into your GO32 environment variable,
   which will redirect stderr to stdout, and redirect stdout to
   a file by appending ``> file''to your command line.  See
   question 5.1 above.

2) You can use a shell smarter then COMMAND.COM, such as 4DOS,
   which knows how to redirect standard error stream to a file.
   4DOS is shareware and can be found, e.g., on SimTel mirrors.

3) You can add ``core file'' to your GO32 environment variable,
   to have your traceback written to the named file.  This only
   works for the exception traceback redirection (useful when
   running graphics applications).

4) You can run your program under any one of the programs which
   save the output of programs they spawn in a file.  I suggest
   using a program called SCRIPT, which is similar to its Unix
   namesake.  It has an advantage of saving everything which
   goes to screen AND showing it on the screen at the same
   time.  SCRIPT can be found on SimTel mirrors as SCRIPT11.ZIP
   (e.g., oak.oakland.edu:/SimTel/msdos/screen/script11.zip).
