Palm Pre Modem Forwarding

It is possible to forward the Pre's modem to your host computer via a usb network connection.

Then you can access the Pre's modem (running WebOS) from your host computer using msmcommd and mdbus2.

Setup

• Cross-compile the serial_forward utility (git.freesmartphone.org) for the Pre (using OpenEmbedded or another cross-toolchain) and copy it over
• Enable usbnet on the Pre:

  usbnet enable

• Connect to the Pre using novaterm:

  novaterm

• Stop the TelephonyInterfaceLayer:

  stop TelephonyInterfaceLayer

• Reset the modem:

  pmmodempower cycle

• Run serial_forward, to forward the modem to you host computer:

  ./serial_forward -n /dev/modemuart -p 3001 -t hsuart

• On your host computer configure the usbnet interface:

  ifconfig usb0 192.168.0.1

• Install libmsmcomm, msmcomm-specs and msmcommd
• Change the connection settings in msmcommds config (/etc/msmcommd.conf) to look like this:

[connection]
# Which type of connection we should use to connect to the modem: network, serial
type = serial
path = /dev/modemuart
# If you want to connect to the modem over a network link you should use the
# configuration below
type = network
ip = 192.168.0.202
port = 3001

• Start msmcommd:

  msmcommd

• Install mdbus2 or any other DBus debugging tool
• Issue the following DBus commands, to setup the modem:

org.msmcomm /org/msmcomm org.msmcomm.Management.Reset
org.msmcomm /org/msmcomm org.msmcomm.Management.Initialize
org.msmcomm /org/msmcomm org.msmcomm.Misc.TestAlive
