Connecting a Modem To connect a modem to your system, complete the following steps: 1. Edit the /usr/lib/uucp/Devices file. For example, for a Hayes compatible 2400 baud modem (where 1a16 is the port where the modem is located), add the following entry in the /usr/lib/uucp/Devices file: ACU cul1a16 2400 hayes 2. 3. 4. Verify whether the serial port is working properly by testing it with a terminal.
Troubleshooting Modem Table 2-5 lists the common modem error messages, their causes, and describes how to troubleshoot modem connections. Table 2-5 Modem Error Messages Error Messages Causes Actions NO DEVICES AVAILABLE The /usr/lib/uucp/devices file is not setup correctly. Edit /usr/lib/uucp/devices to include an entry for the /dev/culnpp file created earlier.

B Peripheral Connections This appendix provides the pin-out tables to connect the communication ports to the peripheral devices. The peripheral devices must be RS-232 compliant.This appendix addresses the following topics: • “RS-232 Asynchronous: DB-25” (page 33) • “RS-232 Asynchronous: RJ-45” (page 35) • “Cabling Pin-outs for HP Proprietory RJ45 and DB25 Devices” (page 38) RS-232 Asynchronous: DB-25 This section provides pin diagrams for a DB-25 cable.
This cable is a three-wire null modem cable. Transmitted data on one end of the cable is connected to Received data at the other end, and vice versa. The male DB-25 end can be plugged directly into most serial terminals and printers without any adapters. The female DB-25 end plugs directly into any RoHS DB-25 serial port.
