[Tokend-Dev] messagebox in tokend

Hello, We at fedict are looking at expanding the BELPIC.tokend with PPDU over transmit functionality. (for secure pinpad readers that support it) The PIN would then be entered on the cardreader, so the PIN protection on the keychain is no longer needed. We would however like to display a message to the user, stating he has to enter his PIN on his cardreader, but we are having difficulties creating those messages from within tokend. Does anyone know if it possible to create a dialog pop up from within a tokend? Wkr, Frederik
