Hello Mark,
Hello All -
I did some digging today and spoke with our engineering. Here is
what the current state of CONSOLE support in the kernel under Turbolinux
for zSeries and S/390 looks like:
* GA Releases (6.0 and 6.5) have 3215 Support. No 3270 support enabled in
kernel by default.
* 2.4.5-3 beta has 3270 enabled, no 3215. I guess that's why it's called
"beta" ;-)
* 2.4.7 alpha release has both 3215 and 3270 enabled.
As noted, you can recompile the kernel (2.4.5) and in the
/usr/src/linux/configs file set "CONFIG_TN_3215=y" to get 3215 support.
As we go forward I believe our inclination will be to leave both types
supported. This is due to the following statement from the current Device
Drivers and Installation Commands manual from IBM for the 2.4.7 kernel
(http://www10.software.ibm.com/developerworks/opensource/linux390/docu/l390dd06.pdf
- see page 27):
==========================================================
The drivers for the 3215, 3270 and hardware consoles can be compiled into the
LINUX kernel. If more than one console is present the default console
driver will be
chosen at run time according to the environment:
* In an LPAR or native environment, the hardware console will be made the
default.
* In VM/ESA either the 3215 or the 3270 console driver will be made the
default, depending on the guest's console settings (the "CONMODE" field in
the output of "#CP QUERY TERMINAL").
* On a P/390 the 3215 console will be made the default.
==============================================================
If anyone begs to differ on this setting please speak up. We'll (naturally)
do QA testing before releasing anything final and console issues will be
looked at.
