I'm having a problem with a DZQ11 interface on my home VAX II and would like
to know if anyone has an idea about it...

Config:  VAXstation II in BA123 worldbox, KA630 CPU, 16MB memory
	 DEQNA, ESDI disk controller, TK50, VCB01 graphics card, DZQ11

Version: VAX/VMS 5.3
	 DECwindows (haven't tried VWS)

Problem: using a modem off any port on the DZQ, I get dropped characters (even
	 if I ALLOCATE the port before connecting to it), and eventually the
	 display halts -- I still get characters passed through the modem, and
	 I can see TD and RD when I type commands, but nothing is displayed
	 onscreen.  Once this condition occurs it can only be cleared by a
	 reboot.  Each port exhibits this behaviour, and killing one port does
	 NOT kill the others.  SET TERM commands do nothing to clear the error.
	 No errors appear on a SHOW ERROR command.

Attempts:
	-tried SET TERM
	-occurs when using SET HOST/DTE or C-Kermit
	-tried reloading TTDRIVER (it's not unloadable)
	-tried ALLOCATing the port before using it.  No effect.
	-occurs on both a Zoom v.42bis 9.6k brand-new modem and on an old DEC
	 Scholar 2400 v.22bis.
	-checked CONFIGURE to make sure CSR and Vectors were okay (they are).
	-ran MDM DZQ11 test, passed...

Status:  Nearly out of hair

Any insights would be appreciated, as would a bottle of Witch Hazel (or maybe
some Monoxodil).
