The verbose mode of the Frankfurt RS-232 CAN4VSCP adapter makes it easy to diagnose a CAN4VSCP bus without any other tools other than the adapter and a terminal program. Registers can be read/written on remote nodes, the interfaces opened in listen, normal and loopback mode and you can even search nodes on the bus. And in addition to the loopback mode there is the CAN4VSCP driver mode which works with the VSCP Daemon and VSCP Works and SLCAN mode which works with SocketCan on Linux.
