commit c0a79c0424a99180ed4c79e3335dc3f7ced2322c Hiltjo Posthuma <hiltjo@codemadness.org> 2020-08-19 22:57:57 +0200 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.
