Function

Transmit a byte over the serial bus

Header

cbm.h

Declaration

void __fastcall__ cbm_k_ciout (unsigned char C);

Description

Purpose of this function is to send a byte of data over the serial bus. In order for the data to be received, the serial device must have first been commanded to LISTEN and been given a secondary address if necessary. This routine always buffers the current character, and defers sending it until the next byte is buffered. When the UNLISTEN command is sent, the last byte will be sent with an End or Identify (EOI).

Limits

  • The function is only available as fastcall function, so it may only be used in presence of a prototype.
