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

status: untested

windows

status: untested

piping to an external program

linux

windows

TODO

  • whether the "UP9600" (daniel dallmann) hack is being used seems to depend on the baudrate(?). this should be a seperate option

driver issues

handling of DTR and RTS seems to be completely missing. rs232dev_set_status, rs232dev_get_status, rs232dev_set_bps apparently are not called by the layer above
