Might as well.  It needs to be offered on any media needed by the user.

Ready for some good news, guys?  I started last night's test about 
10:30pm or so, and it's 7:02pm the next day, 716,000+ sectors have 
been read at 115.2 kbps on a CoCo 2 without errors.  Sometime tonight 
1 million sectors would have been read without any errors, which is 
what I call "satisfactory".  At this point I can leave the low-level 
serial code alone and work on the wrapper and protocol code for 
making all the neat things happen you'd expect over a network between 
two computers.
