I just got an Ipaq 1940 and can't get the infrared to send or receive. I checked the box in connections to receive all signals and also checked the line where it says to receive an infared beam from a pocket pc 2000 or H/pc device. Sent signal with a Ipaq 1910 and won't receive signal. Tried sending contacts with Ipaq 1945 back to Ipaq 1910and won't send either. Any suggestions other than infrared must not work?
