here i will track some things regarding rs232 emulation, and perhaps fix things while at it Gpz (talk) 19:29, 25 July 2019 (CEST)
using a real RS232 port
linux
/dev/ttyUSB0
status: working out of the box
windows
- the windows driver understands various options passed in the so called "mode string" after a colon after the ports name
COMx[:][baud=b][parity=p][data=d][stop=s][to={on|off}][xon={on|off}][odsr={on|off}][octs={on|off}][dtr={on|off|hs}][rts={on|off|hs|tg}][idsr={on|off}]
- finding out what COM port the usb adapter ended up might be tricky, you can use a tool like "Keyspan Serial Assistant"
status: working after some massaging of the code
rs232 over ip
linux
windows
piping to an external program
linux
windows
