VxWorks Shell The vxworks_shell parameter indicates whether or not access to the

VxWorks operating system through a command shell is desired. If this parameter

is set to

TRUE, an option will appear in the main menu of the Freeway Interactive

Menus providing access to the shell. The VxWorks shell allows you to interactively

invoke any subroutine that has been loaded into Freeway’s memory, including

those supplied by the VxWorks operating system, those supplied by Protogate,

and those defined in any of your own application modules that have been loaded

using the

sra_module parameter or via the shell.

Upon the first invocation of the shell, the symbol table for the Freeway server

(

fwyyy.sym

) is loaded from the System Boot Directory to resolve all function ref-

erences called from the shell, unless it has already been loaded to resolve refer-

ences in modules loaded with the

sra_module parameter. Because use of the

VxWorks shell requires at least a working knowledge of the VxWorks operating

system and provides a powerful interface which could cause Freeway to crash if

used improperly, it is recommended that this parameter be set to

FALSE after

development of your customized application modules is complete.

Added Interface Type This optional parameter identifies LAN interfaces to be used by

Freeway in addition to the primary network interface. The primary network

interface is defined in the System Boot Parameters menu (described in

Section 4.5.1 on page 153), either with the Boot Device parameter if booting from

the network or with the Secondary Network Interface if booting from disk. The

types of interfaces supported for the

added_interface_type parameter, and the value

to be used to specify each, are as defined for the Boot Device parameter on page

150.
