or B. Note that port A is considered to be the console port and has no modem dial in capabilities, but may be used for dial out. Port B can be used for DIALOUT or DIALIN use. Port B does provide the required DCD signal for dial-in. This DCD signal tells Solaris ttymon process the modem is requesting a login.
2.)  Configure the modem cable in accordance to the pinouts below.

Signal         RJ45      DB25 Modem

------         ----      ----------

RTS            1    --   4

DTR            2    --   20

TXD            3    --   2

Signal Ground  4    --   1

Signal Ground  5    --   7

RXD            6    --   3

DSR(DCD)       7    --   8

CTS            8    --   5

3.)  Using Admintool, configure the modem for bi-directional.
If unable to run Admintool, Run the command;

#pmadm -a -p zsmon -s ttyb -i root -v `ttyadm -V` -fu -m "`ttyadm -b -S n -d /dev/term/b -s /usr/bin/login -l 38400 -m ldterm,ttcompat`" -y "Bi-Directional modem"

To verify that the service is running use the  pmadm -l  command. You should see something like;

#pmadm -l

zsmon          ttymon         ttyb           u    root     /dev/term/b b - /usr/bin/login - 38400 ldterm,ttcompat login:  - - n  #Modem   Bidirectional

3a.) If you wish to delete the service, use admintool or the following command.

#pmadm -r -p zsmon -s ttyb

4.)  Using TIP, configure the actual modem for dial-in.
This will also sync the modem with the computer to avoid garbage logins.

Note. Always TIP into the modem using the dialin speed used in configuring the login service.

    # tip -38400 /dev/cua/b

Done.
