[comp.sys.ibm.pc.misc] How can I patch DOS 4.0 to have Echo off by default?

fratus@niaid.nih.gov (John Fratus) (11/20/90)

I've looked all over for a patch that I can make to PC-DOS 4.01
to default it to Echo Off. All the patches I've seen (including the
one on SIMTEL) stop at DOS 3.31.

Can anyone point me at the patch?

Thanks!
