If you have the equipment, this can be the easiest method to understand, and is the only method to use for real hardware.
Serial hardware can be tricky to get right, but be persistent. There are a few things to remember.
- Plan which connections are DTE and which DCE, and which gender each has. Know which serial port (1 or 2) you're connecting on each computer.
- Get the right kind of null modem. There are a few ways to make them and not all are the same.
- Use shorter cables as much as possible.
- Use a serial terminal program such as HyperTerminal or Minicom to observe the remote computer. If you don't see data you can recognize, then something is wrong.
- GDB remote commands start with $ and end with ;. You'll be able to recognize them that way.
- Note: use these settings (In HyperTerminal)
Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: Hardware
There are nice cables on the market that are not so expensive (~10 USD) that are well made. This is the best bet.
If you don't get one of those, you can get a small null modem and gender changer and use it to connect a normal serial cable between serial ports.
