Computer system for use with a wireless data communication network

A modem for ensuring effective data transfer between a communication network and Data Terminal Equipment (DTE), the modem including:

• a receiver for receiving a modulated data signal from the communication network;
• a demodulator coupled to the receiver for demodulating the modulated data signal;
• a microcomputer coupled to the demodulator for converting the modulated data signal into a serial data stream, and for generating a connection signal indicating that the modem has entered a data transfer state;
• a delay element for delaying transmission of the serial data stream to the DTE for a predetermined period of time after the modem enters the data transfer state;
• a memory for storing the serial data stream until the predetermined period of time has expired;
• and
• a serial data interface coupled to the microcomputer for transmitting the connection signal and the serial data stream to the DTE.

A programmed method in a wireless modem for ensuring effective data transfer between a remote host system and a DTE via a wireless packet-switched network, wherein the modem is connected between the wireless packet-switched network and the DTE, the method comprising the steps of:

• transmitting data packets from the remote host system to the wireless modem via the wireless packet-switched network;
• receiving the data packets at the wireless modem and storing the data in a buffer within the modem;
• in response to receiving the data, the modem then transmitting a connection service signal to the DTE indicating that the modem is receiving data packets from the remote host system;
• the modem delaying for a predetermined period of time after transmitting the connection service signal to the DTE, while storing any received data in the buffer;
• and
• at the expiration of the predetermined period of time, the modem then transmitting the stored data from the buffer to the DTE.
