10 A: Here's an example for dialling out to an ISP via a modem on
11 /dev/tty02. The modem uses hardware (CTS/RTS) flow control, and the

96 Set up a modem on a serial port so that users can dial in to the
97 modem and get a login prompt.
142 Q: When I try to establish a connection, the modem successfully dials

201 This can also arise with a modem which uses an AT command set if the
205 modem serial port will be set to the same setting.

398 - The modem has to be set to assert CD when the connection is made and

415 modem already does V.42 compression? Won't it slow the CPU down a
421 - The V.42 compression in the modem isn't very strong - it's an LZW

472 possibility is that your modem is set for XON/XOFF (software) flow
620 between the modem and the computer. This auto-detection occurs when
621 the computer sends characters to the modem, when the modem is in
622 command mode. It does not occur when the modem is in data mode.
623 Thus, if you send commands to the modem at 2400 bps, and then change
624 the serial port speed to 115200 bps, the modem will not detect this
625 change until something is transmitted from the computer to the modem.
628 anything. If the modem was already running at the specified speed,
630 modem. To cure this, use an init script such as the following:
632 pppd ttyS0 115200 modem crtscts init "chat '' AT OK"
634 To reset the modem and enable auto-answer, use:
