Black Box 5000 manual DC1

Multiserver 5000

Table 9-8. Asynchronous Channel Characteristics (continued)

Option		Default	Description
7.	XON Character	DC1	Selects the character for the X-ON function. To ascertain which control
			character to select, refer to the user manual of the device attached to the
			port. Choices for the X-ON character are DC1, DC2, DC3, and DC4.
8.	XOFF Character	DC3	Selects the character for the X-OFF function. To ascertain which control
			character to select, refer to the user manual of the device attached to the
			port. Choices for the X-OFF character are DC1, DC2, DC3, and DC4.
9.	Buffer Control	XON/XOFF	Sets the method the Multiserver 5000 uses to control data flow from the
			attached device. There are four buffer-control options:
			• None means that no buffer control will be used, thus disabling the
			Multiserver’s ability to control data flow from the attached device.
			• XON/XOFF means that the Multiserver outputs the X-OFF control
			character (defined in option 7) to instruct the attached device to suspend
			transmission, and to wait for an X-ON character (defined in option 8) to
			resume transmission.
			• CTS means that the Multiserver drops the Clear-To-Send (CTS)
			interface control signal to instruct the attached device to suspend
			transmission, and to wait for CTS to be raised before resuming
			transmission.
			• WANGX provides support for WANG 2200 Computer Systems. See
			Appendix F for information on WANGX applications.
10. Flow Control		XON/XOFF	Sets the method the attached device uses to control data flow from the
			Multiserver 5000. There are five flow-control options:
			• None means that no flow control will be used. The attached device will
			not be able to control the flow of data from the Multiserver. Use this option
			when you have HP 2631 or HP 2635 printers in an HP system that
			operate in a spool mode.
			• XON/XOFF means that the attached device will send the X-OFF control
			character (defined in option 8) to instruct the Multiserver to suspend
			transmission. The Multiserver then waits for the X-ON character (defined
			in option 7) to resume transmission. If this option is selected, code level
			must be 7, 8, or 9. Select this option if Smooth Scroll (for DEC VT100) is
			to be enabled.
			• DTR means that the attached device drops Data Terminal Ready (DTR)
			interface control signal to instruct the Multiserver to suspend transmission.
			The Multiserver waits for DTR to be raised before resuming transmission.
			• XON/XOFF + DTR allows the attached device to use either
			X-ON/XO-FF or DTR flow control.
			• WANGX provides support for WANG® 2200 Computer Systems. See
			Appendix F for information on WANGX applications.
11. CR Delay		0	Configures to provide a delay after sending a Carriage Return (CR), a
12. LF Delay		0	Line Feed (LF) and/or a Form Feed (FF). Delay values are configured in
13. FF Delay		0	number of characters (0-99) to account for required mechanical actions of
			the equipment attached to the port. Valid only for ports configured as
			channel end to terminal (see option 6, above).
