The only way I can imagine to keep RTS low on opens on selected ports, would be to set up a parameter in /proc or /sys ? maybe its management could be added to setserial ? I have a similar problem with many RS485 cards, when the port is opened the card takes the RS485 bus until RTS is turned back down by the opening process. - To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
