This article is from the Apple II Csa2 FAQ, by Jeff Hurlburt with numerous contributions by others.
KERMIT: Available in DOS 3.3 and ProDOS versions, this freeware runs on any Apple II. (On a GS, you need to turn the "DCD Detect" option OFF in the modem control panel.) KERMIT is little harder to set up and use than some other telecom software; but, works fine for Kermit and X-Modem transfers. It supports VT52, VT100, and dumb terminal emulations. ZLink: a ProDOS system program that requires a IIe, IIc, or IIgs. It supports X-modem and Y-modem file transfers; VT100 and partial VT220 emulations. The "macro" program that comes with it is simple, but fine for some things, like auto-entering your password. A nice feature is that ALL the options are shown and set in a single screen display, reached by pressing Open-Apple-?. I used this program quite happily for a number of years, so it is probably worth a download to see if it meets your needs. Talk is Cheap 4.0: An excellent program for the IIe, IIc, or IIgs. It requires an accelerator chip (e.g. a Zip Chip) in a IIe or IIc to communicate over 4800 baud. With the accelerator chip, you're fine up to 19,200 baud. It has an excellent scripting language, which was used as the basis for Spectrum's scripting language. File transfer protocols are X-modem (various types, such as 4K X-modem and 1K X-modem) and Y-modem (for downloads). The manual is a good tutorial for telecommunications. You may be able to find an early shareware version on the net. ProTerm 3.1: This has been the most popular commercial telecom program available for the Apple II. The program supports many emulations, every file transfer protocol I know (including Kermit), and if you have a mouse, it'll give a mouse and pull-down- menus environment. Telcom: Similar to ZLink in features (except no macros), this is a free never- finished commercial product by Jawaid Bazyar for IIgs only. Featuring a mouse- and-menus interface implemented on the text screen, Telcom offers X-modem uploads and downloads, Y-modem downloads, and VT100 or ProTerm Special Extended terminal emulations. Spectrum: This is the ONLY GS/OS telecom desktop program (i.e., standard menus, the system clipboard for cutting and pasting, etc.). VERY strong scripting language that even supports sounds, icons, fonts, colours, clickable buttons (like HyperCard). It supports most terminal emulations, many file transfer protocols (e.g. Z-modem, though not Kermit. Yet). The author and publisher have released version 2.0 and are committed to developing it further. ANSITerm: from Parkhurst Micro Products. Paul Parkhurst's program is supposedly the best colour ANSI graphics available on a GS. It supports macros, many file transfer protocols, and there is a demo version to try out. GS users only. ---------------------------- By: Rubywand Another very good program is Modem MGR from MGR Software. It runs on any Apple II and works with a wide range of modems, 80-column boards, and clock cards. MM supports popular protocols from X-modem through Z-modem and many terminal emulations. ---------------------------- By: Supertimer Agate offers Z-modem. Z-modem is a much better protocol, with a resume function (web browsers should take note) and powerful CRC-32 error checking. Agate was shareware, but the user decided he couldn't accept money for an unfinished product. None of the shareware checks were cashed. I think it is freeware now.
