Host access
Gallagher & Robertson have developed host access software since the founding of the company in 1982. Our speciality is delivery of 100% software solutions that run on new platforms, with no additional hardware or software components needed. We pride ourselves in delivering solutions that fully utilize the platform's architecture, to give performance limited only by the speed of the system, and not by internal limitations in our solution.
G&R solutions for host access can be divided into three groups, each addressing a given host type: UNIX/Linux, IBM mainframe and Bull mainframe. Access to these host systems from a Windows/Linux/UNIX client requires availability of several classes of software on the client:
- Terminal emulation for users who access legacy applications using a screen-based interface
- Application Programming Interfaces (APIs) used by clients applications
- File transfer for high speed exchange of data between the host and client
- Printer emulation for accepting host print output
- Either a gateway to the system, or support for the standard gateways
We offer powerful, robust and reliable solutions in all these areas for the various hosts types.
Gallagher & Robertson Unix/Linux host access products consist of DEC VTnnn and ANSI terminal emulation, and Application Programming Interfaces
Gallagher & Robertson Bull host access from Windows, Android, iOS, Linux and AIX/UNIX systems is based on Bull VIP and Bull DKU terminal emulation and Application Programming Interfaces. For connecting the emulators or your own applications we offer our own gateway product that additionally supports third-party emulations and applications that connect using Telnet or TNVIP.
