Commstar was a ROM based communication software that came with the Pace RS232 interface. It had a terminal for general RS232 communication and software for accessing Viewdata systems such as [[Prestel]].

The limitations of the [[Commstar]] software, and the desire to use more recently developed file transfer protocols (such as [[XModem]]-1k, [[YModem]] and [[ZModem]]) meant that many users chose to use their Amstrad serial interface with third-party software. This included:
* [[Ansiterm]] - a fast AMSDOS utility (also known as ANSI.ARC)
* [[Charley's Comms ROM]] - sideways ROM capable of 4800 baud terminal emulation
* [[ZMP]] - ZModem file transfer under CP/M
A vast range of comms software was available for [[CP/M]], including [[Bulletin_boards|bulletin board]] hosts, offline readers (notably [[CRR]] - CP/M Read and Reply), and many terminals.
