If you use a 115_200 bauds serial line then you should make sure that you
are not sending more than 15 kbytes each second. A USB connection works at
10_000_000 bauds, which causes either overruns or CTS/RTS flowcontrol
depending on whether the converter supports the latter and whether it´s
enabled. I don´t know anything at all about those converters, i´m guessing
using my knowledge of RS232.
