Modem Emulation

Modem Emulation allows you to configure the serial port to act as a modem. The Digi device emulates modem responses to a serial device and seamlessly sends and receives data over an Ethernet network instead of a PSTN (Public Switched Telephone Network). The advantage for a user is the ability to retain legacy software applications without modification and use a less expensive Ethernet network in place of public telephone lines.

Modem

Modem allows you to attach modem devices to the serial port in order to establish or receive connections from other systems and modems.

Note: Click the PPP Configuration link to set up incoming, outgoing or advanced

PPPsettings if the attached modem uses PPP connections. See "System Configuration" on page 31 for more information about PPP settings.
