pc to pocket pc file transfer??

[spamme0]

HP Jornada 548 Pocket PC. TC/CE1.21
Win98SE desktop TC 5.51
Puma serial port IR interface.
IR works fine with active sync.

Put Jornada in receive mode. On Desktop, send file to IR recipient.
Works fine.

Put Jornada in send mode. Connection fails.
IR send window is locked up. After I try this, I can no longer
transmit files from Desktop to Jornada, must reboot desktop system.

Had same problem with Jornada 690, but didn't really need to
transfer to desktop at that time.

How do I set it up to transfer files from Jornada to Desktop?
