Hello,
i have done the following, firstly using PS2:
PS2 IR DISABLE --> OK
PS2 SE ON --> OK
PS2 SERA ON --> Memory Error, try Easy-Setup and Initialize -->
But i don't do it because in principle the Serial Port is ON
After this i boot linux:
Kernel doesn´t recognize the ttyS0.
Execute setserial /dev/ttyS0 irq 4 port 0x03f8 uart 16550A ---> OK
Execute tpctl --rs1=IRQ4 --rs1=0x3f8 --rs1=enable ---> OK, but
the power/mode for rs1 is (error)
Try minicom with another PC ---> NOT OK, Minicom when transmitting
from the ThinkPad get error 5 and it is due to the fact that kernel
didn't recognize the ttyS0, cable and application already tested with
another PC's
So, i proved another way:
Easy-Setup and Initialize
Boot Linux and kernel recognizes ttyS0
Execute: setserial /dev/ttyS0 irq 4 port 0x03f8 uart 16550A -->OK
Execute: tpctl --rs2=disable -->OK
Execute: tpctl --rs1=IRQ4 --rs1=0x3f8 --rs1=enable -->OK, but again
the power/mode for rs1 is (error)
Try minicom with another PC --> NOT OK, Minicom in ThinkPad transmits
correctly, i mean, there are not errors and the info in
/proc/tty/driver/serial indicates that there are TX's, but the another PC
don't receive anything...
I don't know what can be happening, but i suspect that the problem is with
the power management for the serial port 1
Any idea?, and thanks a lot,
Juan Pablo.
