The string valued options + * are the most complicated, since they may include padding information, + * which we describe now. + * + * Intelligent terminals often require padding on intelligent operations + * at high (and sometimes even low) speed. This is specified by + * a number before the string in the capability, and has meaning for the + * capabilities which have a P at the front of their comment. + * This normally is a number of milliseconds to pad the operation. + * In the current system which has no true programmible delays, we + * do this by sending a sequence of pad characters (normally nulls, but + * specifiable as "pc"). In some cases, the pad is better computed + * as some number of milliseconds times the number of affected lines + * (to bottom of screen usually, except when terminals have insert modes + * which will shift several lines.) This is specified as '12*' e.g. + * before the capability to say 12 milliseconds per affected whatever + * (currently always line).
