Citrix Multiuser 2.0

Citrix Multiuser is a customized version of Microsoft OS/2 1.21 that turns it in to a real multi-user operating system. With Citrix Multiuser, users can connect and simultaneously run character cell based applications from remote serial terminals. To prevent users from interfering with each other, it adds security permissions to devices and files. It can use multi-port serial port boards like the Digiboard, or any serial device that has OS/2 1.21 drivers.

Citrix Multiuser OS/2 does not support running Presentation Manager based application or DOS executables, and programs can not use graphics modes. It also does not have support for networking.

This product was released just days before the IBM-Microsoft separation, which was an almost instant fatal blow as Citrix was licensing OS/2 code through Microsoft.

As a result, Citrix Systems had to backtrack and instead focused on making MS-DOS multi-user until eventually they released a Windows NT based version.

The client software application used on PCs to communicate with a server is Citrix Multiuser Link.

Wanted: the DOS based Citrix system.
