[ltp] ThinkPad 600X and TPCTL

[Juan Pablo Martinez Sanchez]

Hi all,

the serial port of my ThinkPad 600X goes ok in win 2000, but i need it to
run
in linux and i have some problems. So, if you could tell me something
about it i'd
be grateful.

The model is a 2645-EYG, the bios version is ITET47WW (11/30/99). The
kernel version is:

>uname -a

>>Linux hobbit 2.4.18 #5 SMP Fri Dec 27 14:16:35 CET 2002 i686 unknown


I'm using libc 2.2.5, modutils 2.4.15, gcc 2.95.3, make 3.79.1.

Once the kernel boots i try the following commands:

>dmesg | grep tty

>>ttyS00 at 0x03f8 (irq = 4) is a 16550A


>cat /proc/ioports | grep serial

>>03f8-03ff : serial(auto)


>cat /proc/interrupts

I have compiled and installed thinkpad and tpctl version 4.1 correctly,
following instructions
in the README file. When i try:

> tpctl --rs1 --rs2

obtain:

>>thinkpad: I have registered to handle major: 10 minor: 170.
>>resource state:                        ioaddr irq#   able? mode/power
>>superio: Super I/O chip (non-virgin) in plug-n-play mode found at port
base 0x2e
>>. :-)
>>superio: I/O ports for Super I/O chip not available, but ignoring this.
>>thinkpadpm: Found APM BIOS version 1.2 flags 0x03 entry 0x48:0x0. :-)
>>thinkpadpm: Power state of device 0x400 could not be got; 0x9999 was
returned as
>> the state -- APM error 0x1
>>   serial port 1:                       0x0    IRQ0 disable (error)
>>   serial port 2:                       0x3f8  IRQ4  enable


And if i try:

>tpctl --rs2=disable --rs2=off --rs1=enable --rs1=on

obtain:

>>tpctl: serial port 1 has been enabled
>>tpctl: serial port 1 power management is disabled
>>tpctl: serial port 2 has been disabled
>>tpctl: serial port 2 base address has been set to 0x4001
>>resource state:                        ioaddr irq#   able? mode/power
>>thinkpadpm: Power state of device 0x400 could not be got; 0x9999 was
returned as
>> the state -- APM error 0x1
>>   serial port 1:                       0x0   IRQ0  enable (error)
>>   serial port 2:                       0x4000 IRQ4 disable



So, i have an error when turning on the serial port 1. I have taken a look
at TROUBLESHOOTING
in tpctl/thinkpad v4.1 but not find anything. Also i have checked my model
is contained in
SUPPORTED-MODELS and it seems to be similar as 2645-7EG (i have power
management version 1.07
and POSI/BIOS version 1.12).
Also, i have taken a look at source file
..../thinpad-4.1/2.4/drivers/thinkpadpm.c in function
apm_bios_call(...) but i lose myself.

If any help or idea to solve this error will be very well received,

Thanks a lot,

Juan Pablo.
