Use zmodem to upload (copy) a file from your Mac or PC up to your UCLink
account. After you initiate the upload on UCLink, you'll need to tell the
telecommunications software on your microcomputer to begin sending the file.
If the file is not regular plain text (but rather it's an executable,
application or compressed file) make sure to send it in "binary" mode.  For
more details, refer to the manual for your telecommunications software.
