If the host and target systems are connected via a serial port, then the debug agent (pdebug) should be started with the following command:
pdebug devicename[,baud]
This indicates the target's communications channel (devicename) and specifies the baud rate (baud).
For example, if the target has a /dev/ser2 connection to the host, and we want the link to be 115,200 baud, we would specify:
pdebug /dev/ser2,115200
The Neutrino target requires a supported serial port. The target is connected to the host using either a null-modem cable, which allows two identical serial ports to be directly connected, or a straight-through cable, depending on the particular serial port provided on the target.
The null-modem cable crosses the Tx/Rx data and handshaking lines. In our PowerPC FADS example, you'd use a a straight-through cable. Most computer stores stock both types of cables.
