Using the Asynchronous Terminal Interface

Connecting to the Terminal Port

The device used for the Asynchronous Terminal Interface (ATI) can be a VT100-compatible async terminal, or a PC running emulation software. The terminal or PC can be connected to the Terminal port directly, or through an external modem.

Ensure that the device you connect communicates using these settings:

 Data rate set to 9.6 kbps.  Character length set to 8.  Parity set to None.  Stop Bits set to 1.

Terminal port settings cannot be changed from the ATI.
