You have to follow the next steps to configure correctly the HP Jornada. First, make a new modem connection. You have to select Start | Settings in your HP Jornada. Then, choose Connections and pick in Modem.
Next, in New connection..., choose the Generic IrDA modem. Choose the modem speed (115200) and pulse on the Advanced button. You only have to change the Flow Control to Software.
Then, pulse the OK button to go to the previous screen and pulse Next. In the Phone number entry, you have to type ''0'' until the box is full. Pulse the Next button and, finally, the Finish button.
Now, we have already configured the HP Jornada to be the client in the TCP connection.
