- Hi all
-
- I have a question relating to archaic technology (namely SVR3), which has
- no STREAMS autopush facility. If one needs to push a line discipline module
- above a STREAMS device driver which has a getty attached, how does one do it?
-
- I can think of two possibilities:
-
- 1) Use the Devconfig file. However (at least in SVR3.0), the only services
- that can be specified are uucico and cu, *not* getty. So one could
- use this for outgoing calls but probably not incoming. Or have things
- changed in SVR3.2? (I don't have SVR3.2 manuals, only SVR3.0 and SVR4).
-
- 2) Have a daemon process which opens the device, pushes the module, and sleeps.
- The assumption here is that when getty opens the device (the second
- open), it is still going to interface through the pushed module. Is
- this the case? If it is, this is probably the simplest solution.
-
- Thanks in advance

- Graham
