[argyllcms] Problems with DTP20 and chartread

I've been using argyll to create rgp profiles using a dtp20 for about
a month now.  I like the profiles it creates much better than those
created by the ColorElite software that came with the device.  I
espcially like the fact that I can make larger targets to improve

But I have been having problems reading charts from the dtp20 in
either tethered or read wirelessly.  I frequently get communications
errors and have to start over.

If I'm doing a 1 or 2 page chart, it is not so much of a problem
because I can keep running it until it succeeds.  But when I do 3 or 4
page charts, I often cannot complete them because I get the following

"Got 'Communication protocol breakdown' (Wrong number of parameters) error.

I have restarted the computer, stopped extra programs etc.

I currently have a 4 page chart on the DTP20 that I would like to
process.  Do you have any suggestions?
