If only one writable character is stored, information of the writable character No. is set to 
“1” (Stored).    The storage information of a specified character code can be acquired by 
using the ATA Card Writable Character Information Acquire Command ([ESC] WG). 

 

 

The storage information of the writable character has a total of 55 bytes.    The writable 
character No. is assigned from 01 to 44, and from 51 to 55.    Therefore, bytes to which 
Nos. 45 to 50 are assigned are sure to be set to “0” (30H).    When the ATA card is not 
inserted in the specified slot, “00H” for the storage information of the writable character 
is returned.
