[comp.sys.mac.comm] comm btw Mac and Pc

eidlheit@bimacs.BITNET (The infamous Gadi Eidelheit) (04/23/91)

        Hi there!

i got my Mac a week ago and i have an old PC too, i have a Good modem to
the PC, and i want to use it to get Mac files as well, in order to
move files from Mac to PC (physically) i get two suggestions

1) buy an external 3.5 drive for PC, and move this to the Mac superdrive,
problem is i don't know if i can move files from the Mac to the PC, can the
superdrive write in MS-DOS format??

2) i can make a direct link btw my PC serial port and the Mac Modem port,
but do i have to buy RS232 for this or the PC modem port will be o.k.???


        If you know this subject, any more information and advice will be
very welcomed.
                                        thanks in advance
                                                Gadi Eidlheit

Yes, the SuperDrive will write in MS-DOS format, as long as you use Apple File
Exchange.

The PC's modem port is an RS232.  The cable you use to connect the two needs
to have the send and receive pins switched.  I believe this is a standard modem
cable for the Mac, but don't hold me to that.  There are two different Mac
Mini Din-8 to RS232 cables.  One is "for printers" and the other is "for modems"but I forget which one has the switched pins in it.

   With the supplied Apple File Exchange Utility or you can use one of the 
two commercial INITs which will display a PC disk right on the desktop.  
I use AccessPC and MacWEEK rated it just slightly ahead of the other one 
(sorry I forget the name).  But if you use similar apps on both the PC and 
Mac, it is worth its wait in *gold*.  My wife uses Excel on a PC at her 
office and she can bring those disks home put them in my IIsi and she 
double-clicks on the file and Excel opens!  Then by just saving the file 
the AccessPC INIT converts the file as it writes it to the disk.  You don't 
have to even wory about from which platform the disk started on!

   The only difference is that her IBM PS/2 Model 70 running windows is 
about 1/2 the speed of my IIsi. :-)

   The PC modem port is just fine.  You will need a Hayes modem cable for 
the Mac, a null modem connector, and a cable for the PC.  A null modem 
cable/connector swaps the transmit and receive lines.  Otherwise both 
machines will transmit on the same wire and receive on the same wire.  
With a null modem cable/connector, the transmit wire from the PC is 
connected to the receive wire on the Mac (and visa-versa).  [NOTE: if the 
Mac cable or the PC cable is a null modem cable, the null modem cable is 
not wanted.]
