Okay, if you take USAT as a model, here's what happened:
The SEC announced halt beginning "on January 29, 1999, and terminating at 11:59 p.m. EST on February 11, 1999."
Indeed, it appears that it began trading again on Feb. 12.
Here's a chart, which looks fine except some bad data on the first day trading resumed: tscn.com
Here's the historical prices:
