My documentation is quite old but it did contain a statement about timeouts just
as you describe. I expected to find the timeout functionality in IO$SETMODE but
I didn't....

Since I posted, I found that there is an extended characteristics
buffer specfied as p2 (see below)

but I can't get it to work.   The code runs, but I still get a 75
second timeout

Format

status = SYS$QIO(efn, chan, IO$_SETMODE | IO$M_CTRL, iosb, astadr,
astprm, 0, address, 0, 0, 0, 0)

Argument

p2=address OpenVMS usage:
 vector_word_unsigned

I tried the address of descriptor for 6 byte item with
short id = 4 and long value = 20

Documented here:

Hmm, it's difficult to determine which IP stack you are using.  First
you are looking in the TCP/IP Services examples, then you quote from a
TCPware manual...  I'm assuming it's TCP/IP Services, and not Process
Software's TCPware.

You need to look at the TCP$C_TCP_KEEPINIT argument for a IO$_SETMODE
call to $QIO(W).  It's documented here:

<http://h71000.www7.hp.com/doc/82final/6529/6529pro_028.html#tcp_set_t...>

Yeah, I had the wrong doc. Thanks!

But I never figured out how to change the timeout. The doc never
explains the input_parameter_list, the P5 argument used with
IO$_SETMODE or IO$_SETCHAR.

I gave up. I am living with the long timeout on initial socket
connects. For reads, I am using IO$M_NOWAIT and a busy loop.
