modem file transfer?

[Trever Furnish]

Ok, I actually *used* to do this frequently, so I'm going to feel foolish when I see the answer, but I think I've blocked that (painfully tedious) part of history out of my memory, so...

Since x-/y-/z-modem tools don't actually handle the modem connection setup and tear-down, how do you use them to transfer files?

I need to use xyz-modem protocols to connect to remote sites (banks, government agencies) to transfer files to them, but I'm not clear on what software to use to initiate the connection.

I mean sure, sz to send a file using zmodem - but it just talks to the terminal - how does one initiate a connection and *then* use sz?

I need to script it up. The only information I've got about the remote end is the protocol they want to use for file transfer (xmodem) and the speed/parity at which to connect.

There's a big gap in my brain where this knowledge used to live? Someone fill it for me?

I use to use Connect Direct and Telamon software for similar kinds of file transfers and I recall them only being more secure than ftp since they provided the user with a less limited command set. Here's a link:

Here's telamon:

How you connect depends upon your devices and HW setup. ISDN? PPP? If you contact telamon they'll provide setup.

At first I thought that maybe the included "kermit" would let you select the file transfer protocol you desired, but man kermit makes no mention of xmodem ymodem. I then did a google search on xmodem hpux and found a couple of links that may work for you.

Good luck

If this were me, I would look very hard at Pcomm+ - available from Ready To Run Software.

I've used Pcomm+ for years under HP-UX; it includes some powerful scripting and is much easier to configure than uucp.

I suppose that I should add that nowadays the price for Pcomm+ is unbeatable - free.

Hi,

The version of Kermit supplied with HP-UX should be able to handle x/y/zmodem protocols.

If you fire up Kermit and type :
check xyzmodem
it should return "xyzmodem available."

You can now use:
set protocol zmodem
show protocol
and this will show you the commands Kermit will use, ie the sz %s stuff.

Of course you'll still need to script Kermit selecting a modem and dialling out, etc.

Kermit has got a fair amount of help built in, just type help followed by the command you want help on. However, I've found the following book invaluable for working with Kermit:

Using C-Kermit by Frank da Cruz & Christine M. Gianone, on Digital Press.

hope that gets you started in filling that gap :)

Darren
