Macro

Notes

This function is passed through to INT 2F/AX=111Eh by the DOS kernel. Error code 12h is returned if BX is greater than the size of the list. Also supported by Banyan VINES, PC-NFS, LANtastic, and 10NET. Supported by LapLink RemoteAccess but returns the local drive letter; the remote drive letter can be obtained with INT 2F/AX=Cxxxh (see INT 2F/AX=C000h“LapLink”). The returned device name may or may not include a colon, depending on the network software
