How to receive a file using taz and xmodem?

Hello friends, i managed to get my ste connected to my linux box via serial and got access to a shell console. The problem i have now is how to get files transferred to the atari disk. I have used the sx command under linux that performs an xmodem transmission for the file specified, and on the other end, i use taz, and go to the receive file then select xmodem, but it always abort the transfer even before it starts. In fact, it never start the transfer. I have read a page when someone got it on his atari, but it doesn't work here. Sending from the atari to the linux box also dont work. I'm asking this because ghostlink dont work on linux, and i doubt that it would work under a virtual machine too.
Any clues?
Thanks in advance!!!!
