- <H1>Modems</H1>
- <P>
- A modem is a modulator-demodulator: it converts the digital
- communication that a computer issues to an analog tone sequence that
- can be sent over a standard telephone line. This Internet Gateway system
- has two serial ports that can be used for modem connections. However, one
- serial port is usually reserved for a console connection.
- <P>
- Most modern modems contain a number of parameters that control their
- operation, such as data compression, error correction, and speed of the
- connection (known as a baud rate). These parameters must be set to
- comply with a modem on the opposite end of the connection; the remote
- modem converts the incoming analog tone sequence to digital data before
- passing it to the destination host.
- <P>
- An outgoing modem call from the Internet Gateway system must contain the
- name and telephone number of the destination host (presumably an ISP host).
- Because the destination host normally maintains a user account to service
- modem calls, the outgoing call must also contain the login name
- and password for the modem account.
