Issue / Question

Why am I not able to press the FIELD EXIT key as I did for the MC9090 and MC9190 to connect to a host when using the MC92N0 with the 5250 keyboard?


The FIELD EXIT key on the MC92N0 sends a scan code of 001B instead of a 000A (FIELD EXIT) or 000D (Enter) before being connected to a 5250 host.

Resolution / Answer


Wavelink has updated the default scan codes for both the Field Exit and ENT key. 
The correct scan code that the FIELD EXIT key should send is 000A but the current scan code being sent is 001B which cannot be used to connect to a host server. 

On older devices such as the MC9090 and MC9190, the FIELD EXIT key on the 5250 keyboards would send a 000D before being connected to a host, as well as after, to allow the users to press this key instead of the ENT key when prompted to ‘Press [ENTER] to connect’. Once the MC92N0 is connected to a 5250 host, then the 5250 keyboard sends the correct scan codes for both the FIELD EXIT and ENT keys.


The issue can be resolved with the release of the following clients:

  • Wavelink TE Client v7.3.175 for the MC92N0 running WM 6.5 OS.
  • Wavelink TE Client v7.3.183 for the MC92N0 running CE 7 OS.


It is recommended to download and install the latest client as the client version listed here is to help resolve the first TE client version issue.
