I setted the flow control to xon/xoff. (set flow-contron xon/xoff). I cutted -8 and added -l /bin/bash. And still no output.
When i maked a bridge between pin 2 and 3 i got the typed characters. So, the terminal emulator works well... But none login prompt
How can I do?
Thanks for any help!

I installed putty on the server and i connected to ttyS0. I maked a bridge between pin 2 and 3 (on the server) and i got the typed characters.
So: the serial port works fine in the desktop and in the dos pc. The problem may be: 1- the cable 2- the getty command!
Please help me !!
Thank you again for any answer!
If you need more infos, please ask me!
ps: I use ubuntu 9.10 karmic koala, and freebsd
Trying now.

mdc(4) Kernel Interfaces Manual mdc(4) Name mdc - DS5100 serial line driver Syntax device mdc0 at ibus? vector mdcintr device mdc1 at ibus? vector mdcintr device mdc2 at ibus? vector mdcintr Description A DS5100 base system (mdc0) provides four asynchronous ports. An optional asynchronous card (mdc1 and mdc2 ) can be added to supply eight additional ports. The mdc ports are used as follows: Port Usage Connector 0 Console port 6-pin MMJ on CPU board 1 Local terminal 6-pin MMJ on CPU board 2 Full modem control port 25-pin D-Sub on CPU board 3 Local terminal 6-pin MMJ on CPU board An optional asynchronous board provides an additional eight lines: 4 Local terminal 6-pin MMJ 5 Local terminal 6-pin MMJ 6 Full modem control port 25-pin D-Sub 7 Local terminal 6-pin MMJ 8 Local terminal 6-pin MMJ 9 Local terminal 6-pin MMJ 10 Local terminal 6-pin MMJ 11 Local terminal 6-pin MMJ The console baud rate is set to 9600 baud by default. You can change this by setting the baud environment variable from console prompt. Each communication port from the serial line controller behaves as described in the reference page and can be set to run at any of 16 speeds. For the encoding, see You can establish the state of port 2 (port 6) by specifying either modem or nomodem as part of the file entry. Restrictions The speed default is to 9600 baud on the console port. The console device must be set for 8-bit character length with one stop bit and no parity. The driver enforces these restrictions; that is, changing speeds with the command may not always work on console ports.
