002- What is a good setup for moving the files I download and
upload between computers?
The standard setup is a "NULL modem" connection. You will need a
NULL modem connector and each computer needs a modem cable and telecom
program. A IIe or II+ will also need a serial card.
____________ ____________
| PC or Mac | | Apple II |
| running a | | running a |
| telecom | <--modem--> [NULL modem] <--modem--> | telecom |
| program | cable [connector ] cable | program |
|____________| |____________|
"NULL modem" means "no modem". A NULL modem connector is just a pair
of connectors wired 'back to back' with a few lines switched so that
each computer views the other pretty much as though it were a modem.
NULL modem connectors can be found at Radio Shack for a few dollars or
you can make your own.
On the Apple II side, you can choose from several good telecom
programs. Since you would like to be able to do z-modem transfers, good
choices include Intrec's ProTerm-A2 3.1 (Enhanced IIe -- IIgs), MGR
Software's Modem MGR (II+ -- IIgs), AnsiTerm (IIgs), and Spectrum
(IIgs). You can also choose from many freeware and shareware programs.
Generally, these support x-modem but do not support z-modem.
If you're running under a current version of Windows, HyperTerm
works very nicely on the PC side. (For sending Text files from PC to
Apple under HT, be sure to uncheck "send line enders" in the ASCII
settings.) If there is a choice of terminal emulations, it seems best
to stick with something simple, such as "TTY". A good NULL modemming
program for running under DOS is Telemate, commonly available as
shareware. Many other telecom programs are available and work fine under
current Windows, old Windows, and DOS. Similarly, there is a good
selection of Mac telecom wares.
To do transfers, you just connect the modem cable from each machine
to the NULL modem connector. If your PC or Mac has a spare COM port, the
connection can remain in place without disrupting normal net connections
through the other COM port.

| telecom | <--modem--> [NULL modem] <--modem--> | telecom |

|____________| |____________|
If you can not use a separate PC or Mac port for your connection to
the Apple II, you can move the PC modem cable connection from your net
modem to the NULL modem for doing transfers or use a switch box.
For a GS, the modem cable should be a "high speed" type which
allows hardware handshaking and this option should be set in the GS
telecom software. The same is true for other Apple II's running at 9600
baud or above.
Set the same format (8-N-1) and baud rate on each telecom program.
(The format will, almost always, already be set to 8 bits-No parity-1
Stop bit.) A good first-try speed setting is 9600 baud. If errors
indicate this is too fast for either machine, you can move down to 2400
baud. An accelerated GS running Spectrum can connect with modern PC's
running HyperTerm at 56k baud or better.
Note: Spectrum (and most other newer Apple II telecom programs) do not
require that you modify Control Panel settings for speed and
handshaking. Since Spectrum directly accesses the GS serial port, speed,
etc. settings are done in the program. (By the way, this frees-up Slot 2
-- the GS modem firmware Slot-- for any peripheral card which needs to
have its Slot set to "Your Card" in the Control Panel.)
Place each program in terminal mode-- often, this is the default
mode. Or, the particular telecom program may have menu items or buttons
you select for specific kinds of transfers.
Next, you will usually select the function (send or receive) on
each machine and the protocol. The protocol should be the same on both
machines. Z-modem is the best choice for most single or multiple file
transfers. For Text files you may want to do an ASCII or Text transfer.
(See discussion in the Telecom: Hardware and Transfers FAQs.) Finally,
you will select the file or files to send or "Open".
Usually, it is best to start Receive on the target machine before
starting Send on the source machine. If you find that one telecom
program or the other does not give you enough time to start Send-- i.e.
it keeps "timing out"-- change the program's "Time Out", "Inactivity
Delay", etc. setting.

From: Jeff Blakeney
You don't need to manually tell Spectrum or other modern telecom
programs to receive a file each time you do a Z-modem transfer. Just
make sure that you have Auto Receives turned ON. In Spectrum the setting
is in the Settings/File Transfer/Receive Options... dialog.

009- Does anyone out there in Net.Land have the pin connections
to use for a GS CTS/RTS hardware handshake compatible
"High-Speed" modem cable?
View is looking into the cable connector/plug at the pins.
