3511's and serial communication?
We have a "console server" (the moral equivalent of a box with a bunch of serial ports running kermit into a series of headless machines) running Redhat Enterprise Linux 3, and we want it to communicate with a 3511 that has two serial ports.
Is it true that we'll need to hook up both of the serial ports on the 3511?
The serial hardware we're using in the console server is:
00:0a.0 Communication controller: Cyclades Corporation Cyclom-Y above first megabyte (rev 01)
Subsystem: Cyclades Corporation: Unknown device 0100
Flags: medium devsel, IRQ 10
Memory at dd800000 (32-bit, non-prefetchable) [size=128]
I/O ports at 9400 [size=128]
Memory at dd000000 (32-bit, non-prefetchable) [size=16K]
...and the two don't want to talk to each other, despite trying ethernet cables with 9 pin shells on its end that should correspond to straight-through serial and "with a twist" alternately.
Does anyone have any suggestions as to what we need to do to get the 3511 talking to our console server? Perhaps more specifically, are the pinouts on the 3511's serial port different from that of 9 pin Sun computers?
Thanks!
