we use Telnet client 7.3.260 (or 7.3.239) on ZEBRA MC3290G WINCE7.0 for connection to GSW Telnet Server and SAP console. On some screens the function keys F4, F5 are not working. With the GSW client the function keys on same screen works correctly. How to make it works with Wavelink product? I am not sure if this can have influence, but we use the CP1250 as client language on mobile terminals.
Through diagnostic FUNC + CTRL + D I can see that values for function keys are correct.
