The WiModem232 is a modem emulator. Are you using a modem cable (not a null-modem cable) or is the WiModem232 plugged directly into the computer? It could be you have some setting wrong (like baud rate) for the WiModem232 that is necessary for this computer's possible serial debug data that is output on the serial port? Try it with a real modem to see if the results are the same.
