I have noticed that if I disconnect the serial port from my usb to serial adapter and leave the dongle in(Aten International Serial adapter, SiS 5571 usb controller), my machine will reset as soon as I [Attempt to] send data from the usb side. So maybe you are losing carrier signal sometime during the transfer. Another machine with a Via 83C572 USB controller does the same thing. Sis is running 4.7 Stable from Jan 2 2003. Via is running 4.6 Stable from Aug 23 2002. -=Bill Hans Lambermont wrote: > Some more info: setting the serial line speed from 115200 baud down to > 9600 does not help; after a few minutes syncing my palmpilot I got > another reboot.
