p3nfs and the 3-fax-modem
March 97. I received a fax-modem as a present! Rudi told me to upgrade
to p3nfs 5.1.
Here is how I use it.
- What I want to do: (1) log in, read email, etc. (2) copy files from
psion to host machine.
- It is important to switch from "Terminal+New p3nfsd" to "Terminal only",
otherwise it is all very slow (this was true under version 4.3 anyway).
This option is under the Unix-protocol menu in version 5.1.
- One way to copy data is to use Bring.
- Trying to get xmodem working.... Rudi says:
Nfsc only uses the Psion builtin X/Y modem support. The S3c is rumored to
have Z-modem support built in.
The X-modem is a quite primitive protocol.
Y-modem extends it with the capability to send more than one file along with
the filename. Z-modem is a more advanced (i.e. faster) protocol, but needs
more memory for his windows, thats why the early psions did not had it.
rz belongs to the only X/Y/Z-modem package I know for UNIX, it is hard to
understand, and the newer versions are copyrighted.
It consists of two programs: rz (receive zmodem) and sz (send zmodem). If
you rename sz to sb then it uses Y-modem as default, if you call it sx,
it runs the X protocol.
If you try to send a file from the unix to the psion, you should start
"sx " in the UNIX-shell, then return to the psion, and receive it
using the 128 byte (default) X modem protocol. As you are using X-modem,
you have to give the local file a name.
I only got the X-protocol working as far as I remember.
