Usage SIR:
# setserial /dev/ttyS2 irq 3
# irattach /dev/ttyS2 -s 1
Usage FIR:
# setserial /dev/ttyS2 uart none
# irattach irda0 -s 1
Note: It seems as if the setserial command here is not really needed,
but otherwise I have to run irattach twice.
Testing:
ppp via sh888 works over SIR and FIR (though i get a 1s ping time to a
machine at the other end of the ppp tunnel).
Printing (ah well, 'cat file.ps > /dev/irlpt0') work with SIR. I
couldn't print over FIR I just got
irlap_change_speed(), setting speed to 9600
irlap_change_speed(), setting speed to 4000000
irport_change_speed_complete()
IrLAP, no activity on link!
irlmp_state_setup() WATCHDOG_TIMEOUT!
in dmesg.
