Help! The Dectalk PC is hosing my clock!

Well, after getting the Dectalk PC2 driver working with Speakup, I never
expected this.  When I'm actively using the Dectalk PC, my clock starts
wondering into the sunset.  For example, by the end of the day yesterday,
it was about 3 minutes slow.  Today, as a test, I set it and then ran a
loop of having ntpdate query the time from time.nist.gov every 60 seconds.
I had it set to query without setting the clock, so I could see how far it
was drifting.  The offsets over just 3 minutes are alarming!

6.317230 seconds slow in minute one, 11.267927 seconds slow after 2
minutes, 16.887154 seconds slow after minute 3, and so on.  If I leave the
computer idle, with ntpd running to constantly adjust the time, it becomes
stable, so it's clearly something that the Dectalk PC is doing.  Has
anybody else had this problem?  For that matter, is anybody even using the
Dectalk PC driver besides me?
