Defines the default translation mode for cards read from a card reader. All subsequent input read from the specified card reader is converted using the specified mode.
SET CARD_READER device-name[:]
When the system is bootstrapped, the translation mode for cards read into all card readers is set at 029. If you do not specify either of the command qualifiers, the SET CARD_READER command has no effect; that is, the current translation mode for the device remains the same.
