Thanks to everybody who sent me results of running the test program.

A table that summarizes this testing is attached below.  The three
cases where the vendor string was garbled did produce an ASCIIZ
string, but its contents included control characters.

since none of the DPMI servers crashed, except DR-DOS 7, which crashes for
every DJGPP program.
