IBM PC - Software - Communications Support - 6024032 Asynchronous Communications Support (6024032) Item number: 6024032 Announcement date: 1981-08-12 Availability date: 1981-08-12 Announcement letter: 281-65 THE IBM PERSONAL COMPUTER From the announcement: This support allows users, with no additional programming support, to use their IBM Personal Computer as a TTY ASR 33/35 terminal. In addition to the interactive terminal support, the package provides for the exchange of program and data files between the IBM Personal Computer and the host system with which it is communicating as well as between two IBM Personal Computers if both have the Asynchronous Communications Support. The Asynchronous Communications Support Program is designed to allow connection to most host systems which support TTY ASR 33/35 terminals. The following terminal parameters may be stored on the IBM Personal Computer or specified interactively at program initiation: * Bit rate (75 bps to 2400 bps) * Parity * Number of stop bits * Line output turnaround characters * Half or full duplex * XON/XOFF support If additional parameter settings supported by the Asynchronous Communications Adapter are needed, the user can expand the program using the BASIC language. The program has operated with VM/370 Release 6 and VM/Systems Product Release 1 on an IBM System/370 Model 158 with an IBM 3705. The User's Reference Manual contains a discussion of the VM system requirements to communicate with the Asynchronous Communications Support. The IBM Personal Computer configuration must include 64KB of memory, the IBM Personal Computer Disk Operating System (DOS), Disk BASIC language extensions, and the Asynchronous Communications Adapter.
