About transferring text-files from //c to Mac

[vitaco@mbox.vol.it (Nicola Vitacolonna)]

To transfer ASCII files from a //c to a Mac, one way is by means of a
serial connection. You'll need a null modem cable. You can buy it (since
you live in USA - not just Italy - probably you'll find it...) or build
it (I made my own cable using the cable connecting the //c to
Imagewriter II... I cut the wires and did the suitable weldings, but I
think (I am not certain, though) that cable should work without any
modifications, at least as regards streams of data FROM the //c.
However, the following is the pin assignment of the serial port (modem
or printer) of the Imagewriter II (directly from the manual); this
should be as the serial port of the Mac:

8 7 6
5 4 3
 2 1

# Pin    Signal    Description           Direction
1         DTR      Data Transmit Ready   Output
2         DSR      Data Set Ready        Input
3         TxD-     Transmit Data -       Output
4         SG (GND) Signal Ground
5         RxD-     Receive Data -        Input
6         TxD+     Balanced Transmit +   Output
7         NC       No connection
8         RxD+     Balanced Receive +    Input
Shield    PG       Protective Ground    


The following is the pin assignment of connector to the serial port of
the //c (viewed from pins that mate with //c):
 
5         1
  4     2
     3

# Pin    Signal
1        DTR       
2        TXD
3        GND
4        RXD
5        DSR

All you have to do is to connect GND pins together, and TxD- and RxD-
respectively with RXD and TXD. 
Now you got the connection!
To try if things work, you can start your //c with no diskette and:
1) press <Ctrl>-Reset to get the prompt
2) press <Esc>-8 to enter 80-column mode
3) type IN#2 <Return>
4) press <Ctrl>-A
5) type T

So you are in terminal mode. Typing 6B will settle the port speed to 300
baud. On the Mac you can use the old program MacTerm, setting the
Protocol ASCII, the 'Echo CR as CRLF' and the baud rate at 300 baud. The
you can start receiving data (from the File menu: 'Start File
Receive...'). Anything you type on the //c keyboard should appear in the
Mac window.
If everything's right, you're ready to transfer text files.
All you need is a communication program on the //c (I used Access//) and
one capable of receiving ASCII files on the Mac (as MacTerm). Pay
attention in setting the same baud rate.
That's all... I heard (and, probably, you too) about ADT, which should
be nice a program for this kind of work as well, (but I haven't tried it
yet). If you need more about pin connections and so on, try this:

it is!)...

Have fun!
