Not great news :(
The computer recognized the serial port on COM5 and ADTPro says that
it is connected. I am using the null modem cable from RetroFloppy for
the //c and the Radioshack cable with the Prolific chipset (I switched
over to this one because I thought this problem was caused by the
other cable.) I set the working directory in ADT where the DSK files
are and set the baud rate in Windows, ADT on the PC and ADT on the //c
all to 19200. When I boot up the //c, I select (R)ecieve, punch in the
filename, hit enter and...Host Timeout.
Any idea what might not be working now?

I really appreciate everyone's help
