[net.periphs] DMF32 driver enhancements wanted

smb@mhb5b.UUCP (06/19/83)

We've just brought up 4.1c on one of our machines; for reasons that
aren't quite clear to me, it has a DMF32.

Now -- the DMF32 is in many ways an admirable board *except* that it
only has modem control on 2 of its 8 asynch lines.  That, I assume, no
one on the net can fix.  But our other problem is that the printer on
this VAX is on the DMF32, and there's no driver for the printer portion
in 4.1c.  Does anyone have one?  (Failing that, does anyone know for
*certain* if the LP25 printer is compatible with the LP11 controller?
Or is there a RS232-LP25 box around?) Also, the modem control code
doesn't seem to work (and the comments imply that it hasn't been
tested); the trouble seems to be that it's using byte instructions to
set bits in word-only registers.  At any rate, we can't seem to get DTR
out of the sucker, though it does detect hangups.  Has anyone fixed
that problem?

Finally, has anyone implemented a network driver compatible with the
DMR-11 driver in 4.1c?  The manual says the DMF32 supports DDCMP, so it
shouldn't be to hard.
