FT2232H & MSP430 BSL

[Miroslav Šinko]

No, takze je to tak. Ak si pocas behu programu nastavite RTS a chcete ho 
zachovat aj pri zmene baudrate, MUSITE nastavit
dcb.fRtsControl = RTS_CONTROL_ENABLE;

Tu je program, predmetny riadok som oznacil //!!!
Bez neho sa to sprava presne, ako v Br na yi, s nim je spravanie OK. Opat 
som to vyskusal na FT232AM, aj MosChip karte.
