An assorted collection of retrocomputing utilities.
This tool allows you to send a single file over RS-232 using the XMODEM protocol. This allows file transfer over
terminal.exe (Windows 3.1) or
hyperterm (Windows 95 and above).
It supports the following config options (set via ENV vars):
FILEa REALATIVE path to the file you wish to send.
PORTThe serial port you want to send it over. Default is
BAUDData rate. Default is 9600 because I am targeting ancient computers.
env FILE=placeholder.png ruby xmodem.rb
- If you do not see
SYSTEM OKon the distant end at startup, you do not have connectivity. Ensure that the distant end has the correct serial port settings.
- Other options (such as data bits and stop bits) could be configurable, but you will need to request it. Pease raise an issue if you have any questions.
STATUS: It works and I use it regularly with a USB RS-232 adapter on Windows 3.1.
Eventually, this will be a drop-in replacement for an analog modem. Will emulate an analog modem connecting to a dialup ISP. Will operate over null modem cable, eliminating the need for a physical modem.
STATUS: Work in progress. Gets you to the 3rd party auth screen of IE5 (Shiva dialer, really) and then crashes.
