Post PC Max Ultra && Linux driver Reply with quote
HI!

I have problem with PCI Max Ultra + linux. Frequency settings works fine but power settings have strange results. Setting power to 0, turns station into stereo and very low TX power (not off as expected).
IF power setting are 1-7 (no difference), the station transmits high power and in mono. Linux driver is version 0.5 (http://www.fscked.org/). I think this driver is for PCI Max plus.

Is there some specifications for PCI Max Ultra and device stereo operation.

----
Update!! Sry for disturbing, problem solved (problem between keyboard and chair

Yep, manual driver modification helps, but right number for good operation is 13 (0xd), because 1 (0x1) locks frequency and pcmax_user -F freq does not work anymore.

I did ugly hack and replaced two lines on linux driver

case PCMAX_SET_POWER:
copy_from_user(&val, (int *)ioarg, sizeof(u8));
pcmax_write_power(val); // removed & 0x7
break;

and hack from previous threads.

io_control |= (PCMAX_PCI_RF_MASK);
replaced to
io_control = power;

So station works in full power, stereo and frequency is tunable.

previous settings

0xc -P 0 - power off or low, stereo
0xf -P 1 - power full. mono

current settings
0xc -P 12 - power low, stereo
0xd -P 13 - power high, stereo
0xf -P 15 - power high, mono
