Thanks, I took a quick look at it. I think, at this point, that in 
order to know if things are going as they should be, I need some sort 
of device to plug in between the cable and the RS-232 pak, to see which 
signals are high/low.

Because I wrote up my little app to drive DSR high (there's only one 
outgoing handshaking line on Mac serial ports, and it's labelled as 
CTS, and it should be high, according to the reports from the system 
calls on the Mac end), and I still only got the first by from the CoCo 
end... once I get my copy of DriveWire, I'll be able to send other 
drivers over to the CoCo, and be able to really see what's going on.
