The following info may help ... >> 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. [Modem to net] | modem cable COM1 ____ |______ ____________ | PC or Mac | | Apple II | | running a | COM2 | running a | | telecom | <--modem--> [NULL modem] <--modem--> | telecom | | program | cable [connector ] cable | program | |____________| |____________| 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. << You can buy a IIgs Hi-Speed Modem Cable from Intrec ... check http://www.intrec.com/store.html and MC Price Breakers ... check http://www.mcpb.com/html/ap2cbls1.html or you can make your own ... >> From: Tae Song (White Wolf) 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?
