Disk Emulation - Currently master, slave, or master and slave drive emulation is fully working.
DOS Redirector Service - The redirector code is still early in development. It will only support DOS versions >= 5.x for the time being as well as only one drive letter/Pi path.
Virtual Network Interface - No development has started on this feature yet.
Serial Console - A PICON.COM utility provides basic access to the UART for debugging, diagnostics, and configuration of the Pi network interfaces when all else fails. Currently terminal emulation support is provided via DOS console and ANSI.SYS. This utility needs a lot of work and is one of the primary volunteer areas of interest.
Other Features - possible future enhancements
NTP/RTC clock setup
Wifi SSD selection and management of access credentials (essentially wpa_supplicant.conf maintenance)
Virtual hard disk image creation, management, and selection
