Note: With the server's online full-time operation, these parameters can be changed at any time. This includes
changing the channel name in order to prevent clients from registering data with the server. If a client has already
acquired an item from the server before the channel name is changed, the items will be unaffected. If, after the channel
name has been changed, the client application releases the item and attempts to re-acquire using the old channel
name, the item will not be accepted. With this in mind, changes to the parameters should not be made once a large
client application has been developed. Utilize the User Manager to prevent operators from changing parameters and
restrict access rights to server features.

Channel Properties - Communication Parameters

The dialog seen under this heading will vary depending on the device driver that has been selected. If a serial device
driver has been selected, a dialog should appear similar to the following.


Users will be asked to provide the following information.

ID specifies the Communications ID that will be used when communicating with devices assigned to the channel.

Baud Rate specifies the baud rate that should be used to configure the selected Communications port.

Data Bits specifies the number of data bits per data word (5, 6, 7, or 8).

Parity specifies the type of parity the data should use (Odd, Even, or None).

Stop Bits specifies the number of stop bits per data word (1 or 2).

Flow Control determines how the RTS and DTR control lines should be utilized.

Use Modem: If planning to use a modem to communicate with devices connected to the port, check this box.
This selection is only available if a modem has been defined for the PC.

If Use Modem has been selected, the next page allows users to select a unique modem to use for each channel.
After selecting a modem, users can set the dialing and modem properties for the channel. Dialing properties
allow users to specify where the call is coming from and how the server should dial an outside line or long
distance number. For these settings to take effect, the phone number must be in canonical format. Use the
Properties dialog to configure the modem, and refer to the modem's documentation for assistance. See Also:
