task_function()

void mw::zimo::ulf::dcc_ein::task_function

(

void *

)

This task is created by the USB receive task when a DCC_EIN\r protocol string is received. Once running the task scans the CDC character stream for strings with pattern senddcc([\d0-9a-fA-F]{2})+\r, converts them to DCC packets and then transmits them to drv::out::tx_message_buffer.

If no further senddcc string is received before the HTTP receive timeout, the USB receive task is created and this task destroys itself.
