For HP sessions only, file transfer capabilities are now available for systems using the MPE host environment. When you are connected in MPE mode, HPXFER is the only protocol available. MPE file transfers are always Rumba Initiated.
MPE file transfers require special setup by the host administrator. Follow these steps to set up MPE file transfers:
HKEY_LOCAL_MACHINE\SOFTWARE\WallData\Office\HP\MPEBOOTSTRAP
The type of the value is DWORD and the value should be set to 1.
