It would be easier to help you if you could show us an examnple model that you want to estimate and indicate which variable(s) are dummy variables. Seeing a dependent variable and at least one or two independent measure would be helpful. Having said that, if you regress a continuous measure on a single dependent dummy measure, the result is simply a difference of two means t-test. The two means being compared are the mean of the dependent measure vor the group coded zero compared to the mean of the dependent measure for the group coded one.
