Re: [parisc-linux] Serial MUX

Hello,

this driver is under development !
This driver can be used on machines having a non-supported
multi-serial interface like a E35/45/55 or some K-series
machines. 

The first and already tested driver is the PDC console
driver, to use only port-0 of the multi serial board
as console. Now an alternative native MUX driver 
is under development, but this driver can currently 
ONLY access port-0 (first port). The multi-line support
is not coded yet, and some short tests by me show
problems (machine hangs up !).

So you cannot access the multiple serial ports, so sorry.

Does this indicate someone is trying to make linux on a E45 usefull? I've
one next to my desk (terrible noise from the disks or fan).

Unfortunately I cannot help developping, but I can do some testing.

I only need it for console.

slight misunderstanding: this driver supports almost all the
non-16550-compatible serial ports used on HP machines.  That includes E,
F-I, K-class and the optional console card used with some D & R class
machines.  It doesn't include "Burgundy", "Silverfox" or "Lego" console
devices.  I'm working on updating the hwdb to reflect this.

Hello,

yes, I want to have E55 (and familiy) supported fully,
and I try to help in development (so far it is possible,
it is hard to get access to HP documentation).

To use the E55 (or family) as a diskless server, it works
(so you can reduce noise at the meantime, the disks cannot
be accessed in Linux - yet !).

For such a diskless operation, you need
	- serial console
	- ethernet
	- core system
All three things are running under Linux.
Again, you can use the PDC CONSOLE driver OR the MUX driver.
Both are accessed via ttyB0 at the moment.

Oh sorry, that's beautiful, that there are so much
machines with the same device type. My knowledge was
here not complete. I only knew the state of the E55 
(family) and of this one K-class machine, Ryan has.
