/dev/cuaXpY

- should be a hardwired device

Verify that getty is running on port and that it is in a pending state, meaning there should be a ? mark in the tty field.

If getty is not in a pending state, then hardware should be checked out per steps 6 and 7. Verification is done by

using the following command:

ps -ef | grep ttydXpY

6. With modem disconnected from port and powered on, the DTR or TR light should be off. When modem is

connected to port, DTR or TR light should come on. Therefore, port is setting DTR or TR., not the modem. If

DTR or TR light remains on all the time, this indicates that the modem has DTR strapped high and setting should be

changed. Check modem users manual for procedure on how to change strapping. For Hayes compatible modems

that are NOT set up with switches, as a minimum, the following AT command AT&F&C1&D2S0=1&W MUST be

set.

7. After modem is connect to port, perform another ps -ef | grep ttydXpY and verify that getty is still in a pending state.

If getty has a port number in tty field instead of a question mark, then the modem has carrier detect (CD) strapped

high. Check modem users manual or contact modem manufacturer for procedure on how to change strapping.

8. At this point modem is ready for call-in use.

9. To set modem up for call-out usage you must check entries in the following file:

/usr/lib/uucp/Devices

You should add the following two lines if they do not exist:

ACU culXpY

= 2400 hayes

Direct culXpY

- 2400 direct

Note 1: If there are any lines that have ttydXpY instead of culXpY, remove them. Dialing devices should NEVER

be used for dialout.

Note 2: The 2400 is the baud rate. Use the appropriate baud rate for your modem.

10. To test call-out ability use the following cu command:

cu -s2400 -1culXpY -m dir

Note:The 2400 is the baud rate. Use the appropriate baud rate for your modem.

After this is entered you should get a message indicating that you are connected. Entering “AT” and return should

give you an OK back, but if it doesn’t this may be caused by the modem’s echo parameter being turned off. So enter

“ATDTphone_number” and listen to modem to see if it dials. If modem doesn’t dial then have modem checked out.

Type ~. to exit the cu (1) command.

11. Modem is now ready for call-out using cu -s2400 phone_number. Read the “Remote Access: User’s Guide” for

more information.

NOTE

If you have problems getting a modem to work, please note the following from the “HP Remote Access: User’s

Guide”:
