Ok, I have managed to get auto-detection to work.
In picport.cc at line 485 I have uncomment the following:
// Start and stop bits must be 1.
// if (!tmp1 || !tmp2) {
// cerr << portname << ": PIC programmer missing or chip fault" << endl;
// return -1;
// }
And this is what I get when I run picprog now:

--ihx32 --output /tmp/pic1.hex

Seems to work.
When I compare this with piklab-prog¹ the differences in the hex-file are
not very big, so I guess that reading is working more or less ;-)

I'll try to do some more testings the coming days.
