KEA was acquired by Attachmate.

After buying both WRQ, Inc. and Attachmate, who had been long-time competitors in the host emulation business, a group of private equity firms announced in 2005 that the companies would be merged under the new ownership. It was announced that Attachmate founder and CEO Frank Pritt would retire at the same time.
