The Question is:
Some legacy code that I'm working on obtains information from an SGEC Ethernet
controller using the IO$M_SENSEMODE + IO$M_RD_COUNT + IO$M_CTRL function in a
This call seems to return various controller statistics in a buffer supplied as
the P2 parameter, including a carrier sense flag, but I've been unable to find
any documentation regarding the format of the data returned.
Do you know where I can find this information?
The Answer is :
There is a third-party package that uses a similar calling interface
and function code -- the OpenVMS Wizard is not immediately familiar
with a similar documented interface within OpenVMS. Such itemcodes
and functions are generally implemented within the particular target
device driver, so details of the driver are central to the question.
If this is an OpenVMS device and device driver, please contact the
support center, and please expect to provide details of the current
software configuration, the call and the system and NIC involved.
Also expect to be asked details of the information being sought,
of course -- there may be other approaches to the goal, obviously.
