Hello Maria,

Given below is the step by step procedure to configure the Modem for Dial-in Service.

Step 1: Connect the modem to the "Remote Console Serial Port (Modem)"

Step 2: Use the GSP CA command to verify that the configuration matches the
following:

Local Console Serial Port bit rate: 9600 bits/s
Local Console Serial Port Flow Control: Software
Local Console Serial Port Terminal Type: vt100 or hpterm
Remote Console Serial Port Modem Protocol: CCITT
Remote Console Serial Port Modem bit rate: 19200 bits/s
Remote Console Serial Port Modem Flow Control: Hardware
Remote Console Serial Port Modem Transmit Configuration Strings:
Disabled
Remote Console Serial Port Modem Presence: always connected


Note: Setting the Local Console Terminal Type is your choice.

Step 3: Use the GSP ER command to set it to "session mode"

GSP> er
ER
Current remote/modem port access: Locked-out
Do you want to modify this configuration? (Y/[N]) y
Remote/modem serial port access options:
[L]ocked-out: Lock out all dial-in access.
[G]SP : Dial-in results in a GSP login.
[S]ession : O/S controls modem for dial-in and dial-out
GSP may page in any mode if modem is not in use.
O/S may use modem in Session mode only.
Please indicate the new mode for the remote/modem console serial port,
or to retain current value. Choose one of (L, G, S): s
New remote/modem port access settings will be: Session
Confirm? (Y/[N]): y
Command execution may take 25 seconds.
Current remote/modem port access: Session

Step 4: Create the callin and callout device files

# mknod /dev/ttyd0p2 c 1 0x000206

# mknod /dev/cul0p2 c 1 0x000205

Verify the device files using lssf and ll

# lssf /dev/ttyd0p2
asio0 card instance 0 port 2 ccitt callin at address 0/0/4/0 /dev/ttyd0p2

# ll /dev/ttyd0p2
crw--w---- 1 uucp tty 1 0x000206 Dec 22 13:23 /dev/ttyd0p2

# lssf /dev/cul0p2
asio0 card instance 0 port 2 ccitt callout at address 0/0/4/0 /dev/cul0p2

# ll /dev/cul0p2
crw-rw-rw- 1 root sys 1 0x000205 Dec 22 13:31 /dev/cul0p2



Step 5: Edit /etc/uucp/Devices and add the following line:

Direct cul0p2 - 19200 direct


Step 6: Edit /etc/gettydefs and add the following 3 lines:
(There must be a blank line above and below the entry)


192 # B19200 SANE CS8 ISTRIP IXANY TAB3 HUPCL
# B19200 SANE CS8 ISTRIP IXANY TAB3 HUPCL
#Modem Login: #192


Note: The "192" in the above lines is a label, which must be
unique in the /etc/gettydefs file. Please make sure it is not already
used for another entry in the file.

Step 7: Edit /etc/inittab and add the following line:

a0:234:respawn:/usr/lbin/uucp/uugetty -r -t 60 -h ttyd0p2 192


Note: The "a0" in the above line is a label, which must be
unique in the /etc/inittab file. Please make sure it is not already
used anywhere else in the file.

Step 8: Start the getty and verify that it is running:

# init q

# ps -ef|grep uugetty

root 1236 1 0 14:12:00 ? 0:00 /usr/lbin/uucp/uugetty -r -t 60
-h ttyd0p2 192


Step 9: Use cu(1) to connect to the modem

# cu -l cul0p2 dir
Connected

If you get "line problem", use the GSP MR command to reset the modem

Step 10: Configure the modem

at&w1
OK
at&f
OK
atz
OK
at&s1&c1&d3&k3&r1&w
OK
atq2$sb19200$ba0#p0s2=128&w
OK


Step 11: Set the country code on the modem

at%t19,0,nn

where nn is the country code. For Switzerland the command would be:

at%t19,0,0d


Hope this helps.
