By default, the Palm Z22 PDA does not have networking stack. This makes impossible to use web browsers like NetFront or Blazer on it. Albeit possible through PPP connections, the Z22 lacks the required libraries to establish connections through that protocol.
These files re-enable the PPP connectivity for that PDA.
To install them, perform a HotSync of the ZIP-contained files and soft reset.
Tutorials about establishing network connections through PPP (e.g. Softick) are not covered by this page.
