                  KILLMER, CFO, TO LEAVE COMPANY AT END OF OCTOBER


MINNEAPOLIS, SEPTEMBER 3, 1998 -- Digi International Inc. (Nasdaq: DGII), the
leading provider of server-based communications solutions, today announced that
the board of directors has authorized the company to purchase up to 1 million
shares of its common stock from time to time in transactions on the open market
or otherwise.  Shares purchased will be used for the company's stock option and
employee stock purchase plans.  Digi has approximately 15.2 million shares of
common stock outstanding.


     "We are confident in the future of our company and remain very committed to
our aggressive strategy to gain increased market share in the open-systems,
server-based remote access market," said Jerry A. Dusa, president and chief
executive officer of Digi International.


     The company also announced that Chief Financial Officer Jonathon Killmer,
56, will leave the company, effective October 30, 1998.


     "After a long and rewarding career at Coopers & Lybrand, I wanted to 
work in an operating environment," said Killmer.  "Digi has been a great 
opportunity. The last two years have allowed be to accomplish many of the 
things that I wasn't able to do in public accounting.  It is now time to 
pursue some other personal interests.  I wish the best for the company."



     `"Digi has benefited immensely from the experience, leadership and wisdom
of Jon Killmer," said Dusa.  "He has helped Digi return to profitability and to
stabilize internal operations.  We will sorely miss him.
