If you are using using Telnet (real Telnet) then you would have to make sure that you are using Telnet with the WiModem. If you don't have matching modes (RAW or TELNET) on each end, you will never get file transfers to work (any protocol). It could be that there is enough latency with your LAN to cause the problem. Stock Zmodem requires <25ms of latency on packet ACKs. You could trying PINGING the WiModem through the LAN and seeing how much latency you have.
