Hi,

Make sure you have a getty running on the port. Look at your /etc/inittab for a getty entry other than console. Note the entry that looks like baud rate at the end of the entry. It is only the entry that corresponds to the baud rate in /etc/gettydefs.

Make sure you are using the correct baud rate.

If you don't find this entry, then use SAM to configure a modem.

Hello,

1. Configure Modem through Sam.

2. If you have modem configuration for HP-UX from the Modem manula configure modem according to that.

3. Check the Modem Cables and ports on Server side.

4. /etc/gettydefs and /etc/inittab are the two main files get configured when your create a modem device for dial in .

5. Check the speed settings on both files.

6. Check the parity (N-8-1 0r E-7-1)

Goodluck

Depending on what kind of system and where you connected it on the system may limit your success.

On Legacy 800's and K-Class --
make sure you use an HP 40233A cable -- or you won't get communications. You can order the cable from HP at 1-800-637-7740.

Pinout is:
CPU Modem
-------------------------------------------
Gnd 1 ---------- 1 Gnd *
TD 2 <--------- 3 RD *
RD 3 ---------> 2 TD *
RTS 4 <--------- 8 DCD *
DSR 6 ---------> 20 DTR *
GND 7 <--------> 7 GND *
DCD 8 ---------> 4 RTS
9 <--------- 22 RI
DTR 20 <--------- 6 DSR
RI 22 <--------- 5 CTS

This cable is non-symmetrical, and may not work if reversed.

On a D-Class -- if you use the Eisa Mux -- you will need to refer to the following Manual for the correct cable depending on the plug type:

http://docs.hp.com/hpux/onlinedocs/5966-8703/5966-8703.html

On A/L/N Classes, use the PCI_Mux and refer to the same manual as the Eisa_Mux.

Most likely, if it is not a cable issue, then you have to set the modem strings to accept software flow control (Xon/Xoff).

Contact the modem manufacturer and ask to speak with someone familiar with configuring their modem in an HPUX environment -- HP initially are looking for modems that have Hardware Flow Control (RTS/CTS) disable -- Data Compression Disabled -- Carrier Detect (CD) and Data Terminal Ready (DTR) controlled by the interface and NOT held high by the modem.

Hope that helps.
