st: Standard Error in logit

["Dott. Paolo Grillo" <Paolo.Grillo@guest.unimi.it>]

Does anyone know how Stata calculates the Standard Error in logistic 
regression (command logit) from the "coefficient" into "OR" form?
The estimated coefficient are trasformed to OR with the formula (e^b 
rather than b).
Empirically this is not true for SE.
Which is the trasformation for Standard Errors?
Thank You in Advance
Paolo Grillo
