Interface allows the Timex to connect to serial printers and peripherals.
The interface has two main modes of operation: BASIC mode allows you to use the range of functions supplied in the RS232 EPROM with an ordinary BASIC program. TERMINAL mode allows you to use your Timex as a terminal to another processor.
The EPROM functions offered permit the user to send, receive and convert bytes between Z80 code and ASCII, as well as check the status of numerous control flags. Received or transmitted data can appear simultaneously on the screen, and received data may be printed simultaneously.
