I'd like to hook my A3000 up to my RiscPC using a null modem cable (partly to transfer files, mostly for fun). My A3000 has the serial port upgrade, and I found a wiring diagram for the cable here:

http://www.riscos.org/csafaq/part2.html#2_8

However, I'm a bit stuck when it comes to software.

I'd like to make a TCP/IP connection to start with. I found PPPServ, and have seen lots of mentions of freenet - but the links to it all seem to be dead. Any other ideas?

Once that's up and running, I guess I'd need something to actually transfer files. Samba and LanManFS? Any other options?

Thanks in advance!

You could use PPPWart and PPPWahl from here: http://www.gag.de/software/index.html

You'll have a true IP connection via the serial port then.

Transfering files: the most efficient one would be to use an FTP server on one side http://www.rosery.net/riscos/
and e.g. FTPc on the other side.

Another option is using Sunfish and Moonfish, UDP should be faster than TCP (which is surely important over a slow serial link!)

ShareFS should work, too - shouldn't it?

I'm wondering if a smiley should be at the end of the above question! Or am I missing irony?

ShareFS only works over Ethernet.
I might be nice if you could have a ShareFS front end to other transports!

I am no ShareFS expert at all, but how should ShareFS know whether it works over Ethernet or something else? Establishing a PPP link between two machines connects them via IP. I would expect that both UDP and TCP work on the transport layer. So as long as both IP addresses are in the same subnet (ISTR that ShareFS cannot be used beyond the same subnet), according to my theory, it should work.

Interesting Steffen. Has anyone had ShareFS working over anything other than Ethernet?
IIRC there was a version of ShareFS within Pace at one point that implemented most of what was needed to get it to work over the internet. e.g. accessing my home RiscPC from my work one!

I always thought it was plain UDP/TCP, except not routable because it used broadcast packets for share discovery. I can't see why it wouldn't work over a PPP link.

For it to be Ethernet-only would require it to use Ethernet packets directly.

This has taken a bit of remembering, in theory there's an undocumented SWI in Freeway, Freeway_Serial that enables broadcast (and therefore ShareFS) over PPP links.

Unfortuanately the only refs I can find to it is me asking a question about it 12 years ago and the original post from a bloke at Acorn.

Ah, the documentation on the SWI

http://www.riscos.com/support/developers/freeway/index.html

"Freeway_Serial

This SWI is for internal use only."

Helpful

Ah ha,

https://www.riscosopen.org/viewer/view/~checkout~/castle/RiscOS/Sources/Networking/AUN/Access/Freeway/c/module?rev=4.11;content-type=text%2Fplain

SYS"Freeway_Serial", 1, "ppp"

Assuming you're using the universal boot ppp module, stick that in a basic file and change "ppp" to whatever the name of the ppp interface is. That should turn it on in theory.
