NetIPC gives you these capabilities. You can do nowait i/o on a socket,
and NetIPC sockets have built-in timers which you can configure in tenth
of second increments (not necessarily reliable at very small values).

This is all explained in the NetIPC 3000/XL Programmer's Reference Manual
HP Part# 5958-8600 (Oct-89). Its also on LaserRom.

I wrote a library of routines callable from Cobol for NetIPC which expose
all of these features you wish to use (and many more). This library,
called QSDK also includes a free copy of our MPE based web server QWEBS.
QWEBS uses the QSDK socket library for all its network i/o. You can
email me directly if you want more information about QSDK.
