I have no idea if Spectrum's Zmodem was designed to be used with
TCP/IP or not.

The problem will probably lie in one of these areas:
Spectrum's handling of special characters passed across the Telnet
connection with Zmodem
Spectrum's internal interface between Zmodem implementation and the
TCP/IP stack
The TCP/IP stack handling of material being passed (there are known
issues)

Have you notified Ewen about this issue directly? He will probably be
able to provide a lot more input on where the problem lies.
