5.1. Graphics terminals

The IRAF system as distributed is capable of talking to just about any conventional graphics terminal or terminal emulator, using the stdgraph graphics kernel supplied with the system. All one need do to interface to a new graphics terminal is add new graphcap and termcap entries for the device. This can take anywhere from a few hours to a few days, depending on one's level of expertise, and the characteristics of the device. Be sure to check the contents of the dev$graphcap file to see if the terminal is already supported, before trying to write a new entry. Useful documentation for writing graphcap entries is the GIO reference manual and the HELP pages for the showcap and stty tasks (see §2.2.6). Assistance with interfacing new graphics terminals is available via the IRAF Hotline.
