The Question is:
Im using TCP/IP Services V5.4 ECO 1.
I want to send big chunks of data from OpenVMS to a PC.
What is the upper limit of a TCP/IP packet I can send using the $QIO service?
IO$_WRITEVBLK using p1/p2 seems to have an upper limit of around 65000!? I have
tried to use the p5 with a descriptor for the data to send and still gets
IVBUFLEN when trying to send large packets (>200KB). Even if I split this
package into several smalle
r described in a descriptor-list I get the same error...
Have I missed something fundamentally??
I can't find any examples that sends large packets of data! Is there any such
examples??
Regards

The Answer is :
$qio transfers with BG devices is limited to 64 kilobytes in V5.4.
There are plans to increase the largest permissible transfer size
in an unspecified future release of TCP/IP Services after V5.4.
