Key features

Key features of CommsGuarantee, which favourably distinguish it from other communication and data exchange software and make it more lucrative, are:

Applicability and versatility

CommsGuarantee can be applied to a broad range of operating systems and hardware:

Pocket PC, Windows 98, Windows NT, Windows 2000, and Windows ME platforms.
Personal and handheld computers on the basis of processor Intel Pentium and compatible processors, running operating system Windows 95, Windows 98, Windows NT and Windows 2000.

Multiple channels flexibility

CommsGuarantee is designed for file transfer through the following communication channels:

Direct point-to-point cable connection (Direct Cable Connection).
Point-to-point connection using a standard landline modem (Standard Modem Connection. In this case, a modem incorporated in the first device/computer calls the other modem connected to the second device/computer.
Point-to-point connection by GSM modem.
Connection through any TCP-IP networks such as Intranet (corporate networks) and Internet networks. For this connection our software provides point-internet-point and point-intranet-point connections. Program can work practically with any types of network: GPS, Radio Networks, GSM ISDN, X.25, HSCSD, etc., and practically with all available hardware.

Operation does not depend on the modem driver

It is especially important for hardware without a driver installed that would correspond to the operating system of the customer computer. In this case, standard resources of an operating system cannot use the modem, while all you need to use CommsGuarantee on the RS-232 interface.

Option of controlling the communication session

Many communications programs have a rigidly pre-set order of operations carried-out during communication session. In the process of organising the customer system of data exchange, this order may need to be changed. For example, there can be a necessity to receive files on the server, process them, then send the result to the client, wait while these files are processed at the customer's site, then receive files and process them once more. CommsGuarantee caters for all that using a simple script language.

Compactness and functionality

The disk space required for CommsGuarantee installation does not exceed 600 kB. This is especially important for the users of handhelds that cannot use resource-consuming comprehensive communication systems. Certainly, the available operating systems have built-in communication resources, but they are not as convenient and easy-to-use as CommsGuarantee.

Functionality and ways of its expansion for new applications

CommsGuarantee can be applied to Pocket PC, Windows 98, Windows NT, Windows 2000, and Windows ME platforms.

Client companies will minimize the communications problems caused by dropped calls by the ability of our communication software to append data by resuming the transfer process from where it left off. This means that in case of interruption during the file transfer process only the remaining information will be transferred after the renewed connection is established.

The program is designed for the file transfer through the following communication channels:

Direct point-to-point cable connection (Direct Cable Connection).
Point-to-point connection using a standard landline modem (Standard Modem Connection). All the main types of modems are supported. In this case, a modem incorporated in the first device/computer calls the other modem connected to the second device/computer.
Point-to-point connection by GSM modem. This option has been developed by PDASet Software and tested for several types of GSM modems.
Connection through any TCP-IP networks such as Intranet (corporate networks) and Internet networks. For this connection our software provides point-internet-point and point-intranet-point connections. CommsGuarantee software can work practically with any types of network: Wi-Fi Wireless LAN systems, GPRS, Radio Networks, GSM ISDN, X.25, HSCSD, etc., and practically with all available hardware, as far as network hardware developers enable Internet connection and organise TCP-IP network.

Presently, mobile communications proposed by CommsGuarantee can be based on GSM devices, GPRS devices and other in the case of TCP-IP connection, i.e. point-Internet-point, when the mobile user connects to the Internet or simply connects to the corporative network. This option can be easily set up with a dedicated line to Internet. The following advantages are obtained in this case: modem spools are not required to be installed at the client site; representatives can work worldwide as far as local Internet providers are available; additional charges can be charged for providing access to Internet, corporative mail, as well as monthly payments for rendering dedicated line to Internet. Another advantage of this approach is a possibility to implement these solutions immediately in areas where radio networks are widely used.

CommsGuarantee can be used as a receiving server or a transmitting point.
CommsGuarantee supports organisation of the authorised data access by the remote units as defined by the administrator.
CommsGuarantee supports execution of the so-called sessions. During the session, the communication script set by the system administrator is fulfilled. The possibility to set the communication script allows adaptation of the program execution for any particular task and corporative requirements (e. g., to receive file, then run a convert program, next send a file package, hang up, etc.). CommsGuarantee is optimised for organizing data synchronisation for different databases, such as Sybase’s DB Remote database.
CommsGuarantee has been developed by high-qualified programmers using the state-of-the-art technologies, which guarantee that the implementations based on the platform will be relevant to the current requirements and future technologies such as GPRS and 3G.
CommsGuarantee has been developed using Microsoft Visual C++ and eMbedded Tools that allow one to integrate the original texts of the program with practically any application.

Software applications for Pocket PC

One of the main goals pursued by PDASet Software is the provision of mobile solutions that can be compact enough to be stored on Pocket PCs. The most popular remote devices based on Pocket PC are the Compaq iPAQ, Casio Cassiopeia and HP Jornada. CommsGuarantee can be applied to Pocket PCs in various configurations with different equipment.

Modem Connection for Pocket PC

For the companies that have no corporative Intranet networks, as well as for the companies that for security reasons object to connect their offices to Internet through a dedicated line, the ideal solution would be to use CommsGuarantee software program in the direct-modem-call mode. In this case, various options exist for the modem connection:

Integrated GPRS/GSM modem.

Mobile modem (mobile phone with modem) connection of Pocket PC via InfraRed or Bluetooth.

A modem can be connected to the COM port of the cradle where handheld is placed. A range of hardware manufacturers such as Casio, Intermec and Symbol provide special cradles for this function.

A special CF/SDIO Port Card (e. g., produced by SocketCom) can be installed into a Compact Flash or Secure Digital IO slot in the handheld and be used to connect a modem.

A special modem (e.g. PRETEC, PROXIM or XIRCOM) can be inserted into and connected to the Compact Flash slot of the handheld.

A special GSM modem (SocketCOM or Nokia) can also be inserted and connected into the Compact Flash slot of the handheld.

Direct Cable Connection for Pocket PC

In case your Pocket PC is equipped with cradle and Compact Flash Card that supports RS-232 port, CommsGuarantee would provide the option of direct cable connection.

TCP/IP Network Connection for Pocket PC (Internet/Intranet)

Both Intranet (corporate networks) and Internet networks are catered for by the CommsGuarantee. CommsGuarantee provides point-internet-point and point-intranet-point connections. CommsGuarantee software can work with all types of network: GPRS, Radio Networks, GSM ISDN, GPRS, X.25, HSCSD and with all industrial standard hardware.

A typical application is where company staff is equipped with handhelds and needs to remotely exchange files with a server. The following system configuration can be recommended.

The local office network to be connected to the Internet provider via a
