1. Burn hsmodem, use FreeMiNT drivers instead. I had problems with 1.16
slip.xdd (data transfer stalled after few kb) so I used 1.15.12 slip.xdd

2. Turn off compression, it will only slow thing down (even on 060).

3. Falcon rs232 chip does not have buffering. I found 115200 speed to be
very unreliable on std Falcon and not reliable even with CT060. 57600 is
much more reliable and useable speed (in fact in mater of succesfully
transferred packets, even faster).
