E9 HH and Mobile Computer Function Keys

For those of you running E9 HH and using Intermec, Motorola or similar units with Windows Embedded Handheld 6.5 connecting via Remote Desktop Mobile, what methods are you using to pass function keys to the host?


In some research/testing I found Intermec's "SR12051500 - Key remap", which works well if you don't use special characters too much. Other than that, rdesktop-ce is another decent solution that works with function keys out of the box.  Of course, neither of these are necessary with Windows CE and the RDP for that OS... 


Anyways, I'd like to hear how you all are coming through using function keys in Epicor HH and how your mobile computers are configured to do so.  


Thanks!  Jim.
