Thanks, Tom.  You're right - a 128 can go up to 9600 baud with just the
RS-232 interface.  I'm not sure if that's specific to Desterm, or if
Dialogue allows it too, but you can only try and find out.

Cheers,
Gaelyne

Two computers connected with a modem should work fine.  One must be set to
receive, one to send.  I haven't done it but it should work.

     Thanks to all for helping me with my download speed and modem to modem
     questions!

     (here are some more!)

     Using NovaTerm 9.5 I cannot find a listing for a Hayes 9600 in the
     "Select Modem" list.  I find Hayes12inv, Hayes24inv, and Hayes34.4inv.
     Should I select the faster modem for my 9600?

     I did this and it seemed to work fine, but when I am in the terminal
     mode, 2400 (my old bps) is still listed in the line at the top of the
     screen.

     I have changed the modem speed withing "Terminal Parameters" to 9600
     and saved it.  Whats happening?

     What else do I need to watch out for to make certain that I am truely
     working at 9600?

     Thanks in advance to your responses!

     Chris

      My question is, what sort of bps download speed can I expect to

      How about downloading to a RamLink?  What kind of bps download
      speed could I expect with that configuration?

You'll get 9600bps (about 960bytes/second) on the modem.  However, the
modem transfer has to wait after each block while to data is being
written to disk.  If you're writing to a stock floppy, the disk
writing time may be as long than the transfer time.  However, writing
to a RL or HD is fast enough (with JD) to be nearly irrelevant.

Yes, he is.   (Sorry I'd of replied sooner, but have been swamped the
last couple of days).

I don't have my manual here. It's in Australia, but I know this is
correct. I was referring to 1541 disks even though I was thinking of
'81's.   Sorry about that.

Unfortunately I can't. Both my 1581's are on a slow boat to Australia
and all I'm using right now is my FD drive for a 3.5 and I can't use it
for comparisons because it's faster than an '81 -- especially when
using it with '81 disks.

 CL> Just one example would be helpful.

Hopefully maybe there's someone else reading this who can help out,
because a comparison would be interesting.

Subject:      Null-Modem Schematics

  Hello,

 To transfer data/prg/etc... , one can make use of the null-modem cable. With
this you don't need any modem also. Only thing has to be done is,plugging this
cable to the computers (just two computers, one to many communication with this
kind of schematics causes data collision).
 After plugging, and loading terminal programs to the computers, just send the
program, from one of the machine and receive it using the other one.
 Schematics for this cable are at the end of this e-mail.

Final notes:

. If you don't have RS232 interface to plug this cable, there is good schematic
s
in the comp.sys.cbm.faq. If someone asks for the schematics, I can e-mail it.

. You can use Novaterm9.5 at c64 side and Lynx at the IBM side for example.

. You have to use same transfer protocol at both sides (eg. xmodem )

. If you want you can put one of the terminal programs into BBS mode.

. In case of not having soldering experience, this cable should be done by
 someone who has. Otherwise a short cut is probable.

. You will built this cable with your own risk.

Subject:      Admin. reminder stuff.

    Greetings all,

    Every now and then most lists send out a reminder about basic admin. stuff
    and so on. This is one of those. Tune out if you already know your way
    around a mailing list.

    =====================

    Perhaps newcomers to the list will appreciate a reminder of how they can
    access the back-issues - (a.k.a archives) - of this list:

    Send email to:

         MX%"[e-mail]"

    The "Subject:" line is usually left blank.
    In the body of the message, use the command phrase:

         index commodor f=mail

    if you want a list of all the archive filenames.  The files will have
    a name-style like "commodor log9402c".  The archive files go back several
    years and will take a lot of time to read.  The numbers refer to the date;
    eg: 94 = 1994, 02 = month 02, c = 3rd week.

    --------------------------

    Alternatively:
    If you want to "get" a particular file, use the command phrase:

         get commodor log9402c f=mail

    in the body of the message.  The "f=mail" thing at the end is important,
    because it forces the listserver robot to d/l the msg via email.

    --------------------------

    This all assumes your system uses the Multinet, (ie: mx%), protocol;
    other systems may need the email-address prefix to read `WINS%` or `IN%`
    or 'JNET%' or `SMTP%` etc.

    --------------------------

    If you want to post a message to the list, DO NOT address it to the
    Listserv as illustrated above.  Use the *list title* instead - eg:

         mx%"[e-mail]"

    Using this form of address will post your message to everyone on the list.

    ----------------------------

    The main thing to remember is:

    a) Commands - (ie: Index, Get, Digest, Subscribe, Signoff etc) - are
       *always* sent to the Listserver;
       in this case - [e-mail]

    b) Messages - (to be posted to the listmembers) -  are *always* sent to the
       list;
       in this case - [e-mail]

    -----------------------------

    In case of problems contact the owners of the list, who are, (1996)....

            Aaron & Allen <[e-mail]>

            Aaron Baugher <[e-mail]>
      and/or
            Allen Smith <[e-mail]>

    Note that the current list-owners name(s) and address(es) can always
    be obtained with the command "review commodor" sent to the listserver
    in the way mentioned above.

    ------------------------------

    The third problem solver address that can be contacted in cases of
    emergency is....

            [e-mail]

    Note that system administrators have quite enough to do without having
    to attend to mundane chores, so contacting the list-owners is the
    preferred first choice.

    --
    Happy keybashing.....Anthony Hawkins.

 Without Daniel Dallman's RS232 interface you cannot use 9600bps comm. on
a stock C64.

 If you have the Swiftlink Cartridge , 38400 bps works fine. If you want
to do it by yourself there is a schematic called 'datapump', which is
something similar to Swiftlink.
BTW: CMD sells the Swiftlink.

 This is normal, since you don't have the Swiftlink UART card.

Subject:      C128 composite monitor cable?

Hello all,

I recently picked up a color BMG monitor with cable that I use on
my C128.  The problem is when the 128 is on, there is no color.
I connected the 128 to a tv and the color works fine so I don't
think that is the problem.  While looking at the comp.sys.cbm faq
I was comparing my DIN connector with the one displayed and they
are different.  The color pin (as listed in the manual) is not
being used.  Actually,  the DIN connector on my monitor cable
doesn't even have all of the pins that are necessary.

Can someone tell me which pins I need to hook up? I understand
that I guess only four of them are used:

sound
lum/sync
color
ground

Is this correct?  I guess what I need to know is which ones go to
which jack on the other end (monitor)?  For instance, does the
sound and ground go on the audio jack, and the lum/sync and color
go on the video?  Is it that simple.  Can I get these parts to
make the proper cable from Radio Shack?  I would really like to
see color on my monitor.

Thanks,

Steven

Hello,

I have a modem that I would like to use the my 128 but as you all
know, I can't connect it to the 64/128 without the interface.  I
have seen the plans in the comp.sys.cbm faq but somehow during my
transition to a WordPerfect document (or at somepoint) the
schematic doesn't quite look rite anymore.  Does anyone know of
another schematic for this simple interface?  Has anyone tried it
any other chip othern than the one in the faq?  It's hard to get
these kind of parts where I live without waiting for the
mail-order (i am kinda impatient ;-) )? Maybe, they have tried
with something from Radio Shack?

Subject:      Using the C128 Z80?

Hello,

Can anyone tell me how the C128 uses its disk drive, video, and
printer while in the Z80 or CP/M mode?  Does the Z80 execute the
CP/M and then the 8502 take care of the rest?  How do you pass
control between the two processors with software?

I am also wondering if it is possible to trap the Z80 I/O port
events on the C128? It is the only why I can see to successfully
emulate another Z80 machine on the C128 (with my current limited
knowledge on the operation of the Z80 in the 128 :)?

Subject:      Re: null modem?

I think I've tried this before in order to play Modem Wars.  If I remember
correctly the only way I could make it work is cut the telephone wire
connecting the two modems and reverse the wires.  I'm not sure but I think
the reason for this is that you have to make sure the transmit wire of one
modem is the receive wire of the other modem.

Try it out if straight through phone wire doesn't work.
