depends what you mean by through a modem, dialed into a network using Microsoft Dialup? You can manage a PIX through the outside interface,the telnet command allows you to specify which hosts can access the PIX Firewall console with Telnet. You can enable Telnet to the PIX Firewall on all interfaces. However, the PIX Firewall enforces that all Telnet traffic to the outside interface be IPSec protected. Therefore, to enable Telnet session to the outside interface, configure IPSec on the outside interface to include IP traffic generated by the PIX Firewall and enable Telnet on the outside interface. I would strongly recommend using VPN client 3.0 with PIX 6.0.1
