AFAIK there's no way to do that in software with Kermit; however, most
modems can do it in hardware: don't drop carrier when DTR is toggled,
that is. So just add the appropriate magic AT command into what you
specify after "set dial init-string". I think AT&D0 will work with
most Hayes type modems.
