1026h OS Prompt

The OS prompt is used for character driven command interface, like the terminal in WorkBench with the drive.

Writing to sub-index 1 is used to send one character to the drive. At the end of each command you need to send a CR(13) LF(10) before the drive will send the response.

Reading from sub-index 2 is used to receive one character from the drive. A single NULL character, 0x00, is returned if no characters are available. No characters being available can occur if a command has not been sent to the StdIn sub-index or if the drive is processing a command and has not yet generated a response.
