- Not sure about 3.2.4 but in 3.2.1 and 3.2.2, RTS/CTS flow control did not
- work as expected. The computer would only honor the CTS line to stop
- output. It would never drop RTS to stop input (maybe I have RTS and CTS
- backwards, but...). You had to use XON/XOFF or, in my case, I have the
- modem connected to a DigiBoard multi-port bord that properly supports
- RTS/CTS.
-
- You were, as far as I know (someone feel free to enlighten me), also unable
- to set RTS/CTS mode for cu and uucp and XON/XOFF flow control always screws
- up uucp. I.e. you had problems either way. Before switching to the
- DigiBoard, I set up my Systems and Dialer files with two node names for each
- system and two dialers, one for locked port/MNP/flow control and one for
- regular.
-
- Seems to me I head somewhere that hardware flow control was suppoed to
- work under 3.2.4. Anybody heard more?
