Slowly making progress.
Removed all explicit module insertions from rc.local
On a cold reboot did:
irdadump (in one window)
irattach /dev/ttyS1
echo 1 >> /proc/sys/net/irda/discovery
That woke my palm up with the waiting for sender message.
Then hitting the sync button gave the response from irdadump.

Approximately eleven of these cycles. I can reinitiate those cycles at
any time by hitting the sync button. You get a different palm address.
Now cat /proc/net/irda/discovery gives:
nickname: IrCOMM, hint: 0x8204, saddr: 0x7d7e66c8, daddr: 0x785d855a
I assume this is showing the reception of packets by my laptop from the
palm and that the linux IRDA is now aware of my palm when it is trying
to sync. At this point only ttyS1 is available to bind to. But pilot-xfer
still does nothing but hang.
[/root]# pilot-xfer /dev/ttyS1 -l
Waiting for connection on /dev/ttyS1 (press the HotSync button now)...
Note that I have successfully used this pilot-xfer to sync over the serial
port to my hardware cradle before.
After fooling about for a while, ifconfig shows:
irda0 Link encap:IrLAP HWaddr 7d:7e:66:c8
UP RUNNING NOARP MTU:2048 Metric:1
RX packets:1197 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:8
The RX packets increase when I induce the cycles. Nothing I do seems to
make the TX packets get off zero.
What now?
