Depends upon what else you're doing besides receiving bytes. Perhaps something to do with wherever the bytes are going? Any other threads doing anything else? What bit rate are you using? What clock rate are you running the CPU at?This isn't a screamingly fast CPU, but I would think it would handle 115200bps--I've done that speed on a slow Atmel ARM7 chip, and that driver's ISR and DSR code looks even less efficient. -- Ciao, Paul D.
