 In the words of "The Brain" -   YYEESS!

 That cleared up my problem totally!  I'm happily reading/writing
tapes; hitting cntrl-C, etc... not a problem in the world.

 [Turns out I had disabled disconnection on my TAPE and CD-ROM
drive, probably inadvertently when I was turning off WIDE negotiation.]

 I'll be happy to; perhaps later this evening.  I've got a lot
of tapes to read/write now :-)

	Thanks again!!!
