ui_ti: explicitly define VMIN and VTIME values for read()

VMIN represents the minimum number of bytes that should be received when the
read(2) function successfully returns.

VTIME is a timer of 0.1 second granularity that is used to time out bursty and
short term data transmissions.

On some systems VMIN is not 1 causing input processing issues.
