On linux, several users are reporting download problems, while on windows everything works fine. Simply toggling the DTR line appears to fix the problem. A possible explanation is that on windows, the SetCommState() function not only configures the serial protocol parameters, but also initializes the DTR and RTS lines. In the libdivecomputer implementation the default state is enabled (DTR_CONTROL_ENABLE and RTS_CONTROL_ENABLE). The result is that the DTR line gets automatically initialized to enabled, and then manually disabled again. On linux, the DTR and RTS lines are not automatically initialized during configuration, and need to be controlled explicitely. The result is that the DTR line ends up disabled without being toggled.
