VLAN_CMD                                                              VLAN_CMD



NAME
     vlan_cmd -

DEFINITION
     A generic VLAN command interface. A VLAN command string is passed in. The
     command string is expected to be a valid, capitalized, two character VLAN
     command with additional parameter characters as required by the command.
     The string must be NULL terminated. Since the VLAN communication protocol
     requires commands to be terminated with a carriage return character
     instead of a NULL, this function sends a carriage return to the VLAN
     controller in place of the NULL character. A pointer to the VLAN response
     string is returned.  If no values are to be returned, a string consisting
     of a single carriage return and the NULL character is returned. Of a
     return value is expected, it is returned as a NULL terminated string with
     the carriage return stripped off. If a VLAN error occurs (eg.  command
     syntax), the error response string is returned (with the CR stripped).
     vlan_errno is not set since no host side error has occurred.

C SPECIFICATION
     char *vlan_cmd( VLAN_DEV
      *vlanptr,char *cmd)

PARAMETERS
     Name           Type      I/O       Description
     vlanptr             VLAN_DEV *       I               pointer to vlan device
     cmd           char *          I         VLAN command character stringi (NULL terminated).

VALUE RETURNED
     If a non-VLAN error occurs, NULL is returned and vlan_errno is set.
     Otherwise a pointer to the VLAN response string is returned.  If a VLAN
     error has occurred, this will be indicated by the response string. The
     response string returned, if any, should be copied to a user buffer
     before the next VLAN command is issued since the response will be
     overwritten by the new command's response.
