A user using Extra 3.5 TN3270 connects to VM system. He is able to do
file transfer to/from PC. If the same user connects to MVS (gets SNA menu)
and select's CMS, file transfer to/from PC to host does not work.
Anyone knows why? Thanks.....

We have a similar problem here. We don't have the fix yet but it appears
VTAM is the culprit. The systems guy is working on it.

IND$FILE through SNA needs a session with a LOGMODE that allows extended
data streams, e.g. D4x32793 (x=a,b,c). If the connection is through 'dial
MVS', the logmode is probably D4x32782 which doesn't allow extended data
streams.

Check out LOGMODE... If the LOGMODE used supports the query bit and the
emulator is not configured to support sturctured fields, SOMETIMES things
get confused and IND$FILE tries sending structured fields anyways...

Not so. IND$FILE has always supported non-extended attribute connections.
But sometimes definitions makes it 'think' that it has an EA connection and
it uses structured fields instead of plain 3270 data streams.

I've supported IND$FILE from '84 until '90. Fortunately not my job anymore.

And hey, if you got MVS/TCP and a decent stack (one that supports EXTRA!),
why are you using IND$FILE instead of FTP. FTP will use a lot less host
resouces and the transfer will be a lot faster...

Bob,
They need to use PC file transfer for printing on local PC printers. They
have PC print program which uses Hallapi (sp). This program downloads report
from host, formats for user's PC printer and prints.

Well, well. Since they are printing a file via IND$FILE and are windows
users they might consider LPR. There is a nice LPD for WinSock in the
various WinSock directories. It works very well with shipping a file to
print from MVS TSO or VM to a Windows Print Manager controlled printer.

The 'catch' here is the formating has to be done on the host, at least as
far as converting from Host to PC control characters (although the CC option
of LPR does handle most cases). Then the rest is up to the Print Manager...

Hi Bob,

What is WinSock???

My version of IND$FILE is 1.1.1 05/14/88. Where can I find a new version?
can someone help me?

I'm trying transfer a file from a IBM-4361 to a RISC/6000, but something
is going wrong. :(

bye

It might be worth to also recall that a tn3270 client supporting TFTP
(or less conveniently FTP) can print with destination filename "PRN".
Especially if taking care of setting that DOS file to raw mode.
Or if the author is asked to do so...

WinSock is teh 'industry standard' API for BSD Socket calls in windows. It
allows apps people to write to the API and the user to then select which
ever TCP/IP stack suits them best.

You got it. Nothing since then, and most likely nothing ever again on it.
It is so old that you can't even find the announcement of it on IBMLINK.

>I'm trying transfer a file from a IBM-4361 to a RISC/6000, but something

What is the client? What is the connection? What is the LOGMODE being
selected (a VTAM trace might be needed). From TSO - ISPF option 6 or from
TSO ready? Lots of questions...

Where are these LPD programs that are capable of running under WINSOCK?

I checked my records and I have found a pretty good Winsock library at:

ftp.cica.indiana.edu in /pub/pc/win3/winsock

I understand that FTP/Software now has a winsock library also...
