SIO Command $CD Base64 Encode Output
Ripjetski edited this page 2023-08-22 21:40:57 -04:00
Table of Contents

This is a command for Device $70 - The FujiNet Device itself (see SIO-Commands-for-Device-ID-$70).

Base64 Encode Output ($CD)

Description

This function retrieves the output buffer containing the base64 encoded data previously input. You can fetch as many bytes up to the length reported by Base64 Encode Length. Any attempt to get more bytes than are in the buffer will result in an error.

DBYT and DAUX must be set to the same value, so that the FujiNet knows the number of bytes to return.

Firmware version required: 1.1 (2023.08.22) +

Parameters

DCB Value
DDEVIC $70
DUNIT $01
DCOMND $CD
DSTATS $40
DBUF a buffer as big as set by DBYT and DAUX
DTIMLO $03
DBYT the number of bytes to send back
DAUX1 the number of bytes to send back (LO)
DAUX2 the number of bytes to send back (HI)
