5.4.17. SYS_SYSTEM (0x12)

Passes a command to the host command-line interpreter. This enables you to execute a system command such as dir, ls, or pwd. The terminal I/O is on the host, and is not visible to the target.


The command passed to the host is actually executed on the host. Ensure that any command passed will have no unintended consequences.


On entry, r1 contains a pointer to a two-word argument block:

word 1

This points to a string that is to be passed to the host command-line interpreter.

word 2

This is the length of the string.


On exit, r0 contains the return status.
