esp8266: Characters missing when reading from UART #4153

Hi,

First, thanks for micropython, its very handy!

But today I got stuck on something weird, it seem that when reading from a serial connection with the UART module it skips some characters. Actually it seems to skip every 16th character so that when calling either uart.readline() or uart.read(value>15) characters are missing.

Could potentially be a problem with an internal buffer that is not emptied/read properly?

For info,
Hardware is Weemos D1 mini pro (ESP8266ex)
Micropython version (latest): esp8266-20180907-v1.9.4-494-ge814db592
