1.8.1 Terminal Initialization

For best redisplay performance, it is very important to set the terminal speed:

stty 2400

Often when running Hemlock using TTY redisplay, Hemlock will actually be talking to a PTY whose speed is initialized to infinity. In reality, the terminal will be much slower, resulting in Hemlock’s output getting way ahead of the terminal. This prevents Hemlock from briefly stopping redisplay to allow the terminal to catch up.

The terminal control sequences are obtained from the termcap database using the normal Unix conventions. The "TERM" environment variable holds the terminal type. The "TERMCAP" environment variable can be used to override the default termcap database (in "/etc/termcap"). The size of the terminal can be altered from the termcap default through the use of:
