I have tried to access this machine both from linux minicom and windows putty.
Moreover, I have two similiar machines. Although their hardware configurations are slightly different and behavior is changing slightly when hardware reconfigure, the resembled problems accures when working via serial.
Particularily, the effect of text transposition present always.
If we will speak about text transposition: is it normal while working via serial?
Is it possible, that large number of processors of fast speed causes this behavior?
