st: Fw: Multiple One-Tailed Tests

I think this must be an easy question but I can't find the answer anywhere on 

Given the following regression,

y = b0 + b1 x1 + b2 x2 + u 

we want to test whether we can reject b1>0 and b2<0. Unfortunately, it seems 
that the Stata test command only allows me to implement the two-tailed version 
(b1=0 and b2=0). I have found some code that allows me b1>0 OR b2<0 but not both 


Thank you in advance for any suggestions.
