confidence intervals on categorical by categorical interactions in logistic regression model

[Lisa Sale]

Hello, I am running a logistic regression model with binary outcome (y01), two categorical independent variables (f and h, both coded 0/1) of interest and several covariates not discussed here.

logistic y01 bn.f#bn.h cv1 

I have interpreted the interaction term bn.f#bn.h but I also want to report the odds ratio and the confidence interval for h1/h0 for f=1, which is

b[1.h]*b[f#h]

. I would appreciate any advice on how to do this. I thought it might be through lincom, but I can't get it.
