I changed the PC link settings on my 5600 (Sharp 1.32 ROM, Special Kernel) from USB-I/O to USB-TCP/IP so I could use OpenSSH. (Which, BTW, is GREAT! ) However, I notice file transfer no longer works, which requires software installation to take a more circuitous route via CF card reader/CF card slot. :? Is this just an inherent weakness of file tranfer and/or USB-TCP/IP, or do I have some setting screwed up?
