MDFS::Software.HostFS Search

HostFS is a filing system that accesses a remote host.

When wanting to implement a system to access a remote server, one of the first questions is what communication protocol to use. Rather than reinvent the wheel, you may as well use pre-exiting protocols. Whatever protocol you use, it is vitally important that the client does not impose its own expectations of the server's capabilities on the user. The client must just pass everything on to the server, and let it decide what its capabilities are.

Tube protocol

BBC using serial HostFS HostFS is the 6502 Serial Tube Client configured as a remote filing system client. It turns the BBC into a Tube client - yes, the BBC Host Processor becomes a Tube client.

The filing system is selected with *HOSTFS. By default, TubeHost expects the client to be using 4800 baud, 8N1 (8bit 1stop 0parity), so use *FX7,6, *FX8,6 or *Configure Baud 6, *Configure Data 5 at the BBC/Master end. The transmission is actually four times the configured speed, so 19,200.
