SINCLAIR QL <--> PC FILE TRANSFER
=================================

   Even if this SENDFILE documentation describes file transfers
between the ill-fated  Sinclair  QL  and  a  PC,  much  of  the
information should be of general interest when considering file
transfers between any home computer and a PC.
   For Sinclair  QL  users  this  file  also  contains  a  list
covering a number of my other QL programs starting from page 5.
If you want  to obtain  programs from  the list,  please direct
these requests to the Quanta librarians, not me.

   Two  programs  belong  to   this   set,   SENDFILE_EXE   and
TAKEFILE_EXE, together with this document in SENDFILE_DOC.

   The author  shall not be liable to  the user for any direct,
indirect   or  consequential  loss  arising  from  the  use  or
inability  to use of any program  or file howsoever caused. The
(nominal) fee  for  the  QL  programs  does  not  include  user
support.

   Comments  of  and  contacts  with  fellow Sinclair QL and PC
users are welcome and encouraged. If you have the  access,  you
can  try  to contact me at Internet email address:  [e-mail]

Short Descriptions

SENDFILE_EXE
Sends ascii files from QL ser2_ port to PC. Works with Procomm,
MsKermit,  and Telix  well up  to 9600  bauds. Has  proven very
reliable when you get the PC settings right. Use ascii download
in the PC  end  of  things.  Includes  optional  conversion  of
Scandinavian characters å ä ö Å Ä Ö into å ä ö Å Ä Ö.

TAKEFILE_EXE
Takes ascii files sent  to ser2_  port from  a PC.  Works  with
Procomm, MsKermit, and Telix, if their settings are right. Baud
rate 300 recommended.  Not entirely  reliable  because  of  the
technical inadequacy of QL ports. PC optional translation of PC
åäöÅÄÖ into  corresponding QL characters.

How it Started

   The following  letter, which  I sent  to Quanta  in February
1988, gives the background of SENDFILE_EXE and TAKEFILE_EXE. (I
never heard about the letter or my cartridge after I sent it to
the former Quanta officials.)

   "Finally having had time  for it,  I have  tried my  hand at
transferring data  between Sinclair QL and  a Zenith laptop PC.
Contrary to my fears it turned out easier than expected.
   The physical connection was made between ser2 serial port of
the  QL and COM1 serial port of Zenith. (Don't ask me about the
pins.) To  receive  normal  ascii  files  (not  much  sense  in
transferring  executable QL files to a PC) I used Procomm ascii
downloading. Having  set Zenith  up I  then tried  sending data
from the  QL with QCODE (v4.1)  terminal emulation program, but
the transfer was painstakingly slow, and lost the linefeeds and
Scandinavian characters on the  way.  I  then  tried  the  copy
commands suggested in  Quanta, but got  stuck in the  PC end of
things.
   This was no good.  Next  I  wrote  a  simple  Turbo  Charged
SuperBASIC program,  which writes the source  file to ser2 port
adding  the   linefeeds   and   converting   the   Scandinavian
characters. This transfer  works  quite  well  at  9600  bauds.
Success. Perhaps not the most elegant solution, but it works.
   Transfer in the  other  direction  has  not  been  quite  as
successful (nor as necessary), but manageable, nevertheless. At
1200 bauds  I first set  up a logfile  in the QL  end of things
using QCODE, and  the  applied  Procomm  and  ascii  upload  in
Zenith. This works reasonably. The scandinavian characters must
be converted, though, prior sending.
   I also  attempted writing  a program  for the  QL to  do the
receiving  (reading from  ser2), but  contrary to  sending this
method  turned out to be error-prone. The programs halts sooner
or later to an XMIT error in reading the QL port. Not much harm
done though,  since in PC to QL  transfer QCODE is fast enough,
even if not so in the opposite direction."

... EOL (end of letter) to Quanta ...

   After  that  letter  I  have  (hopefully)  solved  the  file
transfer problem  in  BOTH  directions,  and  the  results  are
sendfile_exe and takefile_exe.
                           - 3 -

SENDFILE_EXE

   Transfer  from QL to PC seems to be quite easy and free from
trouble after you get your system once (con)figured out.
   To  begin with,  connect your  QL ser2_  port with  a proper
cable to the RS232 port  of  your  PC.  Personally,  I  have  a
Miracle  Systems Modaptor in between my QL and PC, but this may
not  be necessary. As to acquiring  or making the proper cable,
you'll  have to consult your dealer,  or at least your manuals.
The most common  pin connections are  given at the  end of this
chapter.
   Call Procomm communications program (or similar) in your PC.
Next set Procomm baud rate at  the  rate  you  intend  to  use.
Usually  the setting 9600,N,8,1 will work,  but you may have to
experiment depending on  your PC.  It is  advisable to  set the
Procomm  software flow control (XON/XOFF) on, and hardware flow
control off.
   Next, invoke ASCII download in Procomm.
   On  your QL apply EXEC_W SENDFILE_EXE. The program will then
ask  you for the file to be sent, the baud rate (make sure that
the same baud  rates  are  used),  and  whether  you  want  the
Scandinavian characters translated.
   The  transfer should now  get under way.  If everything goes
right, the characters sent  are echoed  both on  the QL  and PC
screens. When  the entire  contents of  the file  have emerged,
press ESC on Procomm to close the file on the PC.
   Scandinavian characters pose  a problem  for us  poor Finns,
since  they are in the 8-bit half on the QL and PC ascii codes,
and what is more, not  even  the  same  for  QDOS  and  MS-DOS.
Therefore  å ä ö Å Ä and Ö are translated into å ä ö Å Ä Ö when
the translation option is  chosen.  If  you  have  to  use  the
Scandinavian  conversion, use Procomm translation table (ALT W)
to convert the latter back into PC Scandinavian characters. The
relevant translations  are  91:142,  92:153,  93:143,  123:132,
124:148, 125:134.
   Two connection diagrams, courtesy of Mr. Antti Ala-Keturi of
the Vaasa University Computer Centre, are given below:

   QL ser2_ 6 pins           PC COM1 25 pins
         1 ----------------------- 7
         2 ----------------------- 3
         3 ----------------------- 2

   QL ser2_ 6 pins           PC AT COM1 9 pins
         1 ----------------------- 5

         3 ----------------------- 3
                           - 4 -

TAKEFILE_EXE

   Transferring data to QL seems  to  be  more  difficult.  The
maximum baud rate which  works is  300 bauds,  and you  have to
pace sending the characters. Proceed as follows.
   Set Procomm  baud  rate  at  300,N,8,1  and  set  "character
pacing" delay to 100 ms in "ascii transfer options".
   Call  EXEX_W TAKEFILE_EXE and give the file name, baud rate,
and whether you want the Scandinavian characters translated. If
the program aborts at this stage (it sometimes will) in an XMIT
error, just call it again.
   On  your PC invoke Procomm upload  option, and use the ascii
upload. If takefile_exe aborts  again,  terminate  the  Procomm
upload  by pressing ESC on the  PC. Call takefile_exe again and
let  it clear the rubbish  from the port, and  then use it once
again. Usually, at least at this stage the system will work (if
not earlier), and you can invoke Procomm upload again.
   The  file is  echoed to  the QL  screen. On  the QL  you can
terminate the  transfer at any  time by pressing  TAB. When the
transfer is  complete, press CTRL Z on  the PC to terminate the
transferred file. Sounds complicated, but it does work.
   Notice, that  if you  terminate the  transfer with  with the
TAB,  there will be some rubbish in  the buffer at the start of
the next  transfer, so it is advisable  to perform a dummy call
of  TAKEFILE_EXE before the next actual transfer. This is easy,
since there is an "again" option in the program.
   In the PC  -->  QL  transfer  the  Scandinavian  translation
should  work without the need  of considering further settings.
(If you  want to delve into  the translation problems, filedump
programs, such  as QL FILEDUMP_EXE and  PC FILEDUMP.EXE, by the
author, may become handy.)
