Having compiled the development (1.1.3) version of dosemu, I find that the com ports in dosemu are now accessed. The only drawback is that something during that initialization stops brltty, but not speakup. however, asap does work fine in dosemu, except that using the numeric keypad (speech pad in asap) sometime causes the whole screen or more to be read rather than the expected word or line. I had tried this off and on for months, so I'm glad to finally have it resolved. For those on debian, the maintainer of this package says he has fixed the bug in the 1.0.2.1--whatever version and the upgrade should be out very shortly. Thanks to everybody who helped with this. Pcdisk and megadots both work!
