Modem for tight coupling between a computer and a cellular telephone
First Claim
1. A modem for connection with a cellular phone and a host computer, the host computer for providing commands according to the conventional land line AT command set to the modem, the modem comprising:
- a host computer communications port for connection with the host computer for receiving commands from the host computer;
a cellular phone communications port for connection with the cellular phone for allowing transfer of data and commands; and
means connected to said host computer and said cellular phone communication ports for receiving commands, including land line AT dial commands, from the host computer and providing commands to the cellular phone, said means for receiving converting received commands that are land line AT dial commands to appropriate cellular phone commands and transmitting said appropriate cellular phone commands to the cellular phone after conversion of said land line AT dial commands,wherein said means for receiving converts received land line AT dial commands by transmitting signal elements to the cellular phone until a delaying dial modifier is received, then transmitting a SEND command, and then performing the operation corresponding to the received delaying dial modifier.

Abstract
A modem which includes connections for both land lines and a cellular phone. The modem contains high and low level routines that allow it to perform standard AT commands rationally when connected to a cellular phone, and further perform additional AT commands that access cellular specific features. An applications software program in a computer connected to the modem can provide a number of options for determining whether to use the land line or the cellular phone when both are connected. First, it can default to the land line and only use the cellular phone if the land line is not available. Alternatively, it can first use the cellular phone and only use the land line if the cellular phone signal strength is not sufficient. Further, cellular file transfer operations can be aborted if the remaining battery life in the cellular phone is insufficient to reliably complete the transfer.
