Tex. Code Crim. Proc. art. 16.17

After the examining trial has been had, the judge shall make an order committing the defendant to the jail of the proper county, discharging him or admitting him to bail, as the law and facts of the case may require. Failure of the judge to make or enter an order within 48 hours after the examining trial has been completed operates as a finding of no probable cause and the accused shall be discharged.
