Section 4.2: Persistent Connections


Use the Persistent Connections Option to enable Persistent Connections using GNU screen. When this option is enabled, TouchTerm will attempt to use GNU screen on the remote host in order to persist terminal sessions across multiple sessions; in practice, this ends up behaving as though TouchTerm has 're-connected' to the same, pre-existing session when re-launched. Since the iPhone SDK does not currently support maintaining connections after TouchTerm has terminated, this is an effective alternative for most situations.

In order for this option to work, the remote host must have GNU screen installed and available at /usr/bin/screen. (Although, see the Advanced Options if this is not the case.)

Please note that due to incompatibilities between GNU screen and the VT100 standard used by TouchTerm, there may be some terminal emulation problems when using screen-based applications such as emacs and vi. We also recommend that you set the Allow Scrollback option to Off when using any screen-based application with Persistent Connections enabled, as this tends to reduce errors caused by the emulation incompatibility. However, if you make frequent use of such programs, we recommend that you leave this option disabled.
