I haven't tried this, but one thing you want to make sure of is that you use a "cross-over" cable. The serial ports on PCs have what's known as a DTE interface (Data Terminal Equipment). The serial ports on modems have what's known as a DCE interface (Data Communications Equipment). A standard serial cable is designed to connect a DTE interface to a DCE interface (i.e. a computer to a modem). What you are trying to do is connect two DTE interfaces together. For that you need to use a special serial cable called a "cross-over" cable which is specifically designed to connect a DTE interface to another DTE interface. If you try to use a regular serial cable, one designed to connect a DTE interface to a DCE interface, it won't work. An alternative to using a cross-over cable is to use a device called a "null modem" on one end of your serial cable. A null modem attached to a standard serial cable effectively converts it into a cross-over cable. Connecting a serial printer to a computer also requires a cross-over cable or a standard cable plus a null modem, since both devices have a DTE interface. You also might have to use two cables and two serial ports. One serial port looks like a modem, with you as the terminal. minicom allocates it. The other serial port looks like a serial console, with you as the host. getty allocates it. The other server sees a similar pattern. -- .''`.
