### Configuring a Device for a Modem

Use these procedures to configure an AccelePort device for a Dial-in or Dial-out modem connection. Configuring a device for a modem requires familiarity with both the operating system and the modem being used. While the following procedures are sufficient for most cases, it may be necessary to take additional steps to properly configure your modem or to set up the operating system for a specific application.

#### Procedure 1: Dial-in Modem Configuration

1. Use the SCO Admin tool to fully configure the modem. Enter:

   `scoadmin modem`

   Use the SCO online help for assistance with scoadmin.

2. Connect to the modem with the following command:

   `cu -l /dev/term/h1D`

   (The device `h1D` used here is just an example.)

3. If necessary for your modem, enable auto-answer by entering this modem command:

   `ats0=1&w`

4. Disconnect from the modem by entering tilde-period:

   `~.`

5. Use the stty or ditty commands to set any required TTY parameters that you did not set in Step 1. For help with stty, see the UnixWare online help. For help with ditty, see Setting TTY Options.

#### Procedure 2: Dial-out Modem Configuration

1. Use the SCO Admin tool to configure the port. Enter:
