I had some luck.

I finally found the programming documentation:

http://www.os2museum.com/wp/os2-history/os2-library/os2-2-0-technical-library/

and now I know (PDF scan) why google searching didn't find it.

I thought this was the right manual:

http://www.os2museum.com/files/docs/os220tl/os2-2.0-pdd-ref-1992.pdf

page 18-93

But this code:

    APIRET rc;
    ULONG tempRead;
    USHORT parm = 1;
    ULONG parmlen = sizeof parm;
    KBDKEYINFO cd;
    ULONG datalen = 0;

printf("about to ioctl\n");
    rc = DosDevIOCtl(0 /* handle */,
                     4, /* category */
                     0x74, /* function */
                     &parm, /* parm area */
                     sizeof parm,
                     &parmlen, /* potentially output */
                     &cd, /* data area */
                     sizeof cd, /* maximum size */
                     &datalen); /* potentially output */
    printf("rc is %d\n", rc);

gave me a return code of 22, which I found out from the
Watcom header is UNKNOWN_COMMAND, and that
seems to be documented here:

This function returns an UNKNOWN_ COMMAND error if the caller is in the Presentation Manager session


Even though I'm running via command prompt. I tried opening
a fullscreen window, but that didn't change anything, ie still
rc 22.

Then I had the idea that maybe I'm not supposed to be using
the Physical Device Driver Reference and I should instead be
using either the Virtual Device or Presentation.

I'm currently downloading those manuals and it's taking a while.

I also checked the Watcom header and found:

bsesub.h: USHORT APIENTRY16 KbdCharIn(PKBDKEYINFO,USHORT,HKBD);

So it's the 16-bit call that was mentioned, and Watcom
must do auto-thunking.

Ideally I wouldn't rely on that and would switch to 32-bit
DosDevIOCtl:

bsedos.h: APIRET APIENTRY DosDevIOCtl(HFILE,ULONG,ULONG,PVOID,ULONG,PULONG,PVOID,ULONG,PULONG);

(note APIENTRY, not APIENTRY16)
