fix escape codes splitting across `getBlockOfChars` #161

Open goertzenator opened 3 years ago

goertzenator commented 3 years ago

This patch adds a 20ms timeout to getBlockOfChars when an ESC character is seen. This forces getBlockOfChars to wait for a whole escape sequence which could otherwise get fragmented on a slow connection.
