See subject. Setting F323 does not work (it is DOS1 error handler). Setting F300 does not work too as when entering BDOS system resets my custom vector back to its own. Function 63h says that it does not work when calling F37D from BASIC environment. The purpose for interception is that I need to perform a task (shut MCU command down) before terminating the disk I/O access to BASIC.
