What does the return status of 20 mean from a SYS$QIOW?

[Jur van der Burg]

As noted before, you're using a LAT function code on an NTY (= tcpip) device. No wonder you get a badparam error in return. It's a decimal number (20), since SS$_BADPARAM has a -F- severity and not -W-.

For your comments, this line is my problem

I_FUNCTION = IO$_TTY_PORT .OR. IO$M_LT_CONNECT

What should be it for an NTY Device?

Thanks for everyone help. As you can see, I never work with OpenVms before.

Eric,

This depends on what you want this code sniplet to achieve !

I would like to connect to it?

As Richard Brodie previously suggested, just try removing the two lines of code that assign the function codes and perform the QIOW - depending upon what you're trying to do that's likely all it'll take.

Y'all might want to ring up Process software.

NTY is a Multinet control device. Here are the programming details:

The $qio functions are here:

Here's the set-up command for NTY device:

Based on what I see on a quick read of the MultiNet documentation, the NTY device is probably already connected to the telnet device.

One of the Process folks may be reading here, or you might want to see if there's a preferred sequence for replacing LAT with Multinet over at the Process site. NTYCP is apparently deliberately set up to mimic LATCP.

What I don't know is if there's a $qio that allows you to establish the telnet connection to the printer under program control, if you're looking to do that. Otherwise, you can use a static NTY mapping.

The solution is you do not have to connect to an NTY device unlike an LAT device, which I bet everyone knew except for me.

The only step is to assign the channel before the read.

Thanks for the help.
