# Suggested IRQ usage:

#COM port	Product		 jumpers to install
#========	=======		 ==================
#COM3 	on 	TS-5500 use IRQ5 (install jumper on HD3)
#COM3 	on 	TS-SER1 use IRQ5 (install jumper IRQ5)
#COM3-6 on	TS-SER4 use IRQ5 (install IRQ1+IRQ4 and COM2+COM1)
#COM4 	on 	TS-SER1 use IRQ6 (install jumper IRQ6)
#COM4-7 on 	TS-SER4 use IRQ6 (install IRQ2+IRQ4 and COM4)

#Note:

#It's not possible for us to detect a TS-SER1 or TS-SER2
#Please uncomment the corresponding lines if you are using one.
#By default the TS-SER1 and TS-SER2 start at com port 3
#if you are using a base board with more than 2 com ports
#(ie TS-5500 or TS-5700) you need to change the jumpers and
#change the ttysX to the corresponding com port/s

#If you have a TS-SER1 uncomment the following line
#setserial -v /dev/ttys2 auto_irq autoconfig

#If you have a TS-SER2 uncomment the following two lines
#setserial -v /dev/ttys2 auto_irq autoconfig
#setserial -v /dev/ttys3 auto_irq autoconfig
