     It may help to summarize and expand upon a few things. 

     The Connection is between the Apple II Super Serial Card (SSC) and a COM
port on the PC, usually COM-1 or COM-2.  (The PC Printer Interface port will
not work.)


     To actually make the mechanical connection to a 9-pin COM port on the
PC, you will need whatever combination of cables and adaptors it takes to get
from a 25-pin connection on the SSC to a 9-pin COM port connector for the PC.
Usually PC com ports (9-pin or 25-pin) expect the cable to have a female
connector. (This helps protect against plugging into the PC printer port by
mistake.)

     A straight-through 25:25 cable (one with no swapping around of lines)
plus straight-through adaptors (e.g. 25-to-9) should work for most serial
connections between a PC and an SSC with the "Jumper Block" set to "Terminal"
(Printer). The "Jumper Block" is the thing with the arrow on it. (According
to my notes, the arrow would be pointing down for "Terminal" jumpering.)

     All SSC "mode" settings (via dip switches and/or software) would still
be for "communications" (modem) mode. For more about this, see
http://home.swbell.net/rubywand/Csa2T1TCOM.html#013 .
 
     I do not own an SSC and have not tried the setup. However, the original
ADT docs say that straight-through cable(s) with the SSC Jumper Block set for
"Terminal" (Printer) operation is a setup that works.


     As already mentioned, where ADT is concerned, Hyperterm is used just to
transfer ('type in') the Apple II part of ADT. Since there is no flow control
or error checking during this transfer, you use a low baud rate and long a
"Line Delay". The long Line Delay gives the Apple II time to enter each line
of input.

     Here is an example of creating a good 300 baud Hyperterm setup for
'typing in' Text to the Apple II:

1- Start Hyperterm, get past any intro window (e.g. click "Cancel"), and 
select "New Connection" in the Files menu.

2- "Phone Number" page
Connect using= Direct to Com 1 (or whatever PC Com port you will use)

Click on Configure and set
  Bits per second= 300
  Data bits= 8
  Parity= None
  Stop bits= 1
  Flow control= None
 (You should not need to change any Advanced settings)
  Click OK

Click on the "Settings" page tab

3- "Settings" page
Terminal keys is selected
Emulation= Auto Detect
Backscroll buffer lines= 500

(You should not need to change Terminal Setup)

Click on ASCII Setup
  Send line ends with line feeds is _not_ selected
  Echo typed characters locally is not selected (probably does not matter)
  Line delay= 400 milliseconds
  Character delay= 0 milliseconds

  Append line feeds ... is not selected
  Force incoming data to 7-bit ASCII is _not_ selected
  Wrap lines that exceed terminal width is selected
  Click OK
 
4- Click OK again to finish. Then, click Files and do a Save As to save the
new setup under the name "A2at300.ht" (or any other .ht name you like).


     From the time the setup is saved, whenever you start Hyperterm, you can
click Files and select Open and pick your 300 baud connection setup from a
list which will include A2at300.ht and any other setups you have created.


     To send ADT you would start Hyperterm, select "Open" in the Files menu,
and pick A2at300.ht.

     On the Apple II, you would boot DOS 3.3, enter IN#2 (for an SSC in Slot
2), and set the speed to 300 baud by typing these three characters-->
<ctrl-A>6B
.

     Then, in Hyperterm, you click on Transfer and pick "Send Text File".
This will get you box for browsing to the place adt.dmp is located. Select
adt.dmp and click on "Open".

     You should see characters being typed on your Apple II screen. At the
end of the send, ADT should be saved to your DOS 3.3 diskette (the drive will
turn ON and stuff will be written to disk).


     For doing disk image transfers it seems to be a good idea to move or
copy the .dsk files you want to send to the Apple II into the same folder
which has the ADT program (adt.exe). To get going, you go to MS-DOS mode, get
to the folder which has ADT, and start adt. The PC ADT screen will prompt you
to enter the Com port and baud rate (usually 9600 or 19200).

     On the Apple II, you boot DOS 3.3, INIT however many disks you will need
to receive the disk images, and BRUN ADT. Remove the ADT disk and stick in an
INITed disk. Set your baud rate the same as that set on the PC.

     A good first check is to try a Directory command. If the PC directory
shows up on your Apple II screen you are ready to try a Receive.

     ADT can send only standard non-compressed 5.25" .dsk files (length =
143360 bytes) to the Apple II; and, it can transfer only non copy protected
16-sector 5.25" diskettes to the PC as .dsk files.
