6.2 Pseudoterminal Driver Features

The terminal portion of a pseudoterminal is similar to a regular terminal. The pseudoterminal driver provides the following features:

  • Type-ahead buffer

  • Specifiable or default line terminators

  • Special operating modes, such as NOECHO and PASTHRU

  • Escape sequence detection

  • Terminal/mailbox interaction

  • Terminal control characters, such as Ctrl/S and Ctrl/Q for starting and stopping output, Ctrl/O for discarding output, and all other special characters that are handled by the standard terminal driver

  • Limited full-duplex operation (simultaneously active read and write requests)

For more information on these features, see “Terminal Driver Features”.
