Advanced Port Configuration

This section contains the information you need to configure the following advanced parameters, shown in Table 10, in the Port Configuration window.

Table 10. Advanced Port Configuration Parameters

Parameter	Description	Default
Modem Parameters	Lets you specify the following:
	Dial Type---Sets tone or pulse dialing.	Tone
	Leased Line---Specifies whether the port is connected to a leased line.	No (Dial)
	Modem Init String---Adds additional modem strings to be executed after the modem script. For example, specify `ATM0` to turn off the modem speaker.	None; 36-character limit
Link Parameters	Lets you specify the following:
Note: For dial-in ports, the Link Parameters option is used only for direct connections.	Initial Data Rate---Sets the port speed between the server and the modem.	9,600 bps for direct connections; otherwise, the maximum speed supported by the modem and port
	Initial Data Bits---Sets the number of data bits sent per character.	8
	Initial Parity---Sets parity checking for the parity bit.	NONE
	Initial Stop Bits---Sets the number of stop bits transmitted per character.	1
	Initial Flow Control---Sets hardware and software flow control.	Based on the selected modem type
Port Mapping	Shows the relationship between the port and the physical hardware. The field has the format (x,y,z), where: x = driver name or number y = board name or number z = port number For example, (COMX,0,0) indicates that COMX is the AIO driver on the port, the first zero is the board number, and the second zero is the port number.	Not configurable by the user
Groups Assigned To	Allows you to select the groups in which the port will be a member.	ANY_PORT
Applications Allowed	Limits port access to the AIO or AIOMGR application.	Any Application
Application Parameters	Used by other applications that use the communication ports, for example, e-mail services. Refer to the application-specific documentation for information about what is required for this field.	Not applicable to remote access

To specify advanced port configuration, complete the following steps:

Access the Port Configuration window by following this path:

Select Configure NIAS > Remote Access > Configure Ports > a port name > Additional Parameters

Select Modem Parameters, press Enter, then specify the following parameters:

Dial Type---Specify Tone or Pulse.

Leased Line?---Specify Yes for a leased line or No for a dial line.

Modem Init String---Enter a string of up to 36 characters.

Select Link Parameters, press Enter, then specify the following parameters:

Initial Data Rate---If you are using a modem, you do not have to change this parameter. Make sure the data rate matches the communications equipment.

Initial Data Bits---Select 5, 6, 7, or 8 bits. Set to 8 for ARAS and PPPRNS. The sizes displayed depend on the settings supported by the communications adapter controlling the port.

Initial Parity---Set to NONE, ODD, EVEN, MARK, or SPACE.

Initial Stop Bits---Set to 1, 1.5, or 2.

Initial Flow Control---Set to one of the following:
HDW/OFF, SW/OFF for connections with no flow control. This is the correct setting for multiplexed connections and dial-in connections if the port is attached to modems capable of 2,400 bps or less.

HDW/ON, SW/OFF for connections with hardware flow control only. This is the correct setting for dial-in connections if this port is attached to modems capable of 9,600 bps or higher.

HDW/OFF, SW/ON for connections with software flow control only.

HDW/ON, SW/ON for connections using both software and hardware flow control.

IMPORTANT: If you are using modems, remote access automatically sets the data rate and flow control based on the selected modem type. For direct connections, make sure that the data rate, data character size, type of parity checking, and stop bits used by the remote access port match those used by the remote hardware and software.

Select Groups Assigned To and press Enter.

The groups that this port is a member of are displayed.

NOTE: If you have not defined any group names, you see only the default group name ANY_PORT. You must define group names before you can assign the port to a group. Refer to Creating Port Groups.

Select one or more groups and press Enter.

Press Ins to display a list of additional available groups.

Select Applications Allowed and press Enter.

Press Ins and enter one of the following options for the application name:

AIO---Allows AIO applications written for earlier AIO releases to access the ports.

AIOMGR---Allows new applications written to the AIOMGR interface to access the ports.

CONNECT---Allows remote access applications written to the Service Selector interface (for example, PPPRNS, ARAS, or NCS) to access ports.

The default is Any Application.
