terminal. Both must be connected to phone lines.
Before using modems with your system, check the following:
1. Make sure each modem is connected to the system.
2. Make sure the modem is properly installed and connected to a phone
jack.
3. Set controls on the modem according to instructions in the modem user's
guide.
Before using the modem connected to the remote terminal, check the
following:
1. Make sure the modem is properly installed and connected to a phone
jack.
2. Set controls on the modem according to instructions in the modem user's
guide.
3. Check the settings on the terminal attached to the modem. Depending
on the type of modem and the type of lines used, the baud rate may
be 300, 1200, or 2400. Other settings should be the same as those
described in the previous section.
Before using a phone line with modem support, you must set certain
parameters such as line speed. See your system software manuals for
details.
