Now we're ready to add a modem to the system. This will use the same port monitor that we used for port “A” (ttymon), only it will be configured slightly different to suit our modem.
To configure this we'll follow similar steps to the earlier configuration for port “A,” although we don't need to update the _sactab file as we already have a valid ttymon configured and running. We simply need to add a secondary service and let the existing ttymon manage both of them. This time we'll use a different set of values for the port, because it will be configured for a modem rather than a terminal. The ones we'll use are shown in Table 14.7.
