- In the same vein, is there some magic to make a Sun serial port on, say,
- an IPX respond to hardware flow control. In my case, I am trying to use
- a serial smart switch to share a PostScript printer. Only one of the
- input serial ports to the smart switch is enabled at a time and this is
- done in the serial smart switch by asserting DTR. Hooking DTR from the
- smart switch to various inputs on the Sun serial port and playing with
- various stty setting as well as printcap and ttytab settings resulted in
- no joy. The Sun IPX just merrily spits stuff out the serial port
- irregardless of the handshaking lines. And yes, I did RTFM. Is there
- some obscure detail that neophyte administrators like me often miss?
- Should I waste more net bandwidth with more details?
-
- Thanx in advance.
