IrREADY Serial Port Profile / IrModem Profile

Draft Version 0.9

1 INTRODUCTION

1.1 Symbols and Conventions

The application profile must use the following scheme to define the support for individual features. The following symbols are used:

M	Mandatory support. Refers to capabilities that shall be used in the profile.
O	Optional support. Refers to capabilities that can be used in the profile.
C	Conditional support. Refers to capabilities that shall be used in when certain other capabilities
	are also used.
X	Excluded. Refers to capabilities that may be supported by the device but shall never be used
	in this profile.
N/A	Not applicable in the given context. It is impossible to use this capability.

Some excluded capabilities are capabilities that, according to the relevant IrDA specification, are mandatory. These are features that may degrade operation of devices following this profile. Therefore, these features shall never be activated while a device is operating as a device within this profile.

Terminal

Gateway

Figure 1 IrDA Dial Up example between a mobile phone and a laptop PC / PDA

The typical usage model of Infrared Serial port is described in the Figure 1. Device A (PC or PDA) always does role of Initiator and Device B (ME or TA/GW) always does role of Responder. In NDM, Device B side is waiting for connection from Device A. Device A is configured to DTE side and Device B is configured to DCE side.

		Support in DevA	Support in DevB
1	IrCOMM Initiator	M	N/A
2	IrCOMM Responder	N/A	M
3	DTE Device	M	N/A
4	DCE Device	N/A	M

2.2 User Scenarios

The Ir Serial Port Profile covers the following usage case:

Setting up virtual serial ports (or equivalent) on two devices and connecting these devices with IrDA to emulate a serial cable between the two devices. Any legacy application may run on either of the two devices as if there were a real serial cable connecting the two devices (with RS232 control signals)

The following restrictions apply to this profile:

•The profile supports only one connection at a time i.e. point to point configurations

•This profile does not provide emulation of [GSM0710]. There is no provision for any multiplexing above the IrDA virtual serial port in this profile.

Interface

IrCOMM is the IrDA emulation of RS-232 [232-F] serial ports and the Centronics parallel ports specified in [IrCOMM].

Serial Port Emulation is the entity emulating the serial port or providing an API to applications specified in [IrCOMM Annex ].

Application includes legacy applications that would normally make use of a cable RS232 connection.

2.4 Conformance

If conformance to this profile is claimed, all capabilities indicated mandatory for this profile should be supported in the specified manner. This also applies for all optional and conditional capabilities for which support is indicated. All mandatory capabilities, and optional and conditional capabilities for which support is indicated, are subject to verification as part of the IrReady certification program.
