A direct link constitutes a connection between two Data Terminal Equipment (DTE) devices. The devices must be fooled into thinking they are communicating with a Data Communication Equipment (DCE) device. The way to get around this is with a null modem.
The minimum pinning configuration shown in Table 7-3.
IRIS A | IRIS B |
---|---|
2 Transmit Data | 3 Receive Data |
3 Receive Data | 2 Transmit Data |
7 Signal Ground | 7 Signal Ground |
Attach the null modem cable to serial port two (ttyf2) on the local and remote workstations.
Note: For more information on cables and modems, see IRIX Admin: Peripheral Devices, Chapter 1, "Terminals and Modems."
