ACIA driver
|
|
|
|
Manage I/O from an asynchronous communication interface adapter
|
|
(ACIA). provides "(emit)" to put c char on the ACIA as well as
|
|
an input buffer from which a provided "(key)" reads. This driver
|
|
installs an interrupt handler at RST38 to handle RX.
|
|
|
|
To use, begin by loading declarations (B582) before xcomp is
|
|
loaded. These declarations provide default values for ports and
|
|
memory offsets that you can override. See B582.
|
|
|
|
Then, in the driver part, load range 583-588.
