Serial port 1 data loss occasionally

[yzh03]

Hello JerryChang,

We use the TTL-USB convertor to connect nanokit to PC, and use serial tool “serial port utility” to send data “12345#” per second loop.
The terminal enter “sudo cat /dev/ttyTHS1” after nano is started, and it displays data such as “5#2345##45#45#12345#2345#12345#2345"etc, but no"12345#12345#12345#12345#12345#”.

Thanks!
