This software will help you transfer software to your classic Macintosh (e.g. MacOS System 6, 7, 68k Macs, etc) using the serial port. Very simply, this software runs on a modern host computer, and behaves like a BBS would back in the day. You connect your Macintosh to the host computer using serial, and then, using your vintage computer, you can search and download files from online archives (e.g. Macintosh Garden, Mac Repository). However, this "BBS" has only one user, you!
I don't see why you couldn't use this pseudo-BBS to transfer software to other kinds of computers as well.
This module implements a serial-level interface to the inexpensive USB-enabled geiger counters (available on Amazon) manufactured (or probably OEM'd, based upon how their docs read) by GMC. Does most of the fiddly stuff automagickally so you spend more time pulling data out of your sensor than you do figuring out how to pull data out.
A Minicom like Serial Communication program in Python that adds standard shell features like autocompletion, command history, inline help. It reproduces the behavior of Minicom, adding some features like command history, autocompletion, inline help, and optional pattern highlighting.
Auto-completion and inline help are available using a dictionary file.
Minimal dumb-terminal emulation program. Good for interacting with microcontrollers and occasionally routers.
his package ports the XMODEM, YMODEM and ZMODEM protocols to Python. We try to implement the protocols as minimalistic as possible without breaking the protocol specifications. All modem implementations must be given a getc callback to retrieve character data from the remote end and a putc callback to send character data.
This module encapsulates the access for the serial port. It provides backends for Python running on Windows, OSX, Linux, BSD (possibly any POSIX compliant system) and IronPython. The module named "serial" automatically selects the appropriate backend.
This python script will detect modem events like DTMF Digits, Busy Tone, Silence etc from phone line using Raspberry Pi 3. Seems to do audio signal analysis to do this.
An open source device to connect a computer with an RS232 serial port to a telnet BBS. It does not use an analog phone line but internet through a wifi connection. Behaves like a Hayes dial-up modem, and it is designed and built for old computers. Plug it in, fire up a terminal emulator, and use the Hayes AT command set to tell it what to do. Can theoretically be used with any computer that has an RS-232 port.
Occasionally the designer sells them on eBay, but you can build your own.
Picocom is a tiny (< 40k) terminal emulator program which does little more than open and close serial ports and let you interact with whatever is on the othe end. They don't get much smaller than this. Perfect for debugging serial (or serial-over-USB) devices.
