I have an Apple IIe computer with a Super Serial Card, and I want to
create disk images to copy to the PC where I can run them on a
simulator.  I have attempted several times to use ADT (1.20 and 1.22)
and I keep getting an error when attempting to transfer at least a test
file.  Not sure what I am doing wrong or if there is a problem with the
Apple computer.  When I enter the name of the file to send and send it,
I get garbage on the Apple screen, followed by "any key", and an invalid
code 1C received on the PC side.  I have downloaded ADT from a number of
sources and repeated the installation process many times to rule out the
possibility of a bad copy of the software, but the situation is 100%
repeatable.  The odd thing is, all other functions work fine.

     If all other functions work-- mainly, you can get a dir of the PC
folder on your IIe-- then, you are in pretty good shape. At least, your
A2 ADT is talking to the PC adt.exe program.


     Here are a few things to check:

o- The disk you are trying to send must not be copy-protected. Most
original commercial A2 diskettes are. A fairly good check is to see
whether the diskette can be copied using Disk Muncher, COPYA, or some
other plain whole-disk copier. If it can be copied, it should be
sendable via ADT. (Note that this does not absolutely guarantee that it
will work correctly on an emulator.)

o- You are running the PC side of ADT under DOS. Current versions of ADT
do not run correctly in a Windows MS-DOS window.


     It is possible (but not especially likely) that your copy of ADT122
is corrupted in the areas which deal with transfers. If you have not
changed your ADT configuration-- i.e. have not used the CONFIG util or
otherwise SAVED changes to ADT-- then, you can type in and run a short
program to check your ADT file:


ADTCK for ADT v1.21, ADT v1.22, ADTGS (v.90), ADTgs (v.91)

 10  TEXT : HOME
 20  PRINT  CHR$ (4)"BLOAD ADT,A$4000"
 40  FOR I = 0 TO 2579
 50 Z = Z +  PEEK (16384 + I)
 55  IF I / 500 =  INT (I / 500) THEN  PRINT "CURRENT SUM= ";Z
 60  NEXT I
 70  PRINT "CHECKSUM= ";Z

     A pretty good experiment is to see whether you can Receive a .dsk
disk image (from PC) on diskette (on your Apple II).  The target
diskette should be freshly DOS 3.3 INITed.

Note: By the way, it is a good idea to set your Drive (on the Apple II)
to Drive 2. This helps avoid overwriting your ADT diskette (which can
happen if you use Drive 1 and forget to swap in a blank, DOS 3.3 INITed
diskette for a Receive).  Putting a write-protect tab on your ADT
diskette is another good safety measure.

     The file that you want to receive should be a 140k .dsk disk image
located in the same PC folder as the adt.exe program file.
