5. Loadable drivers

5.1 Graphics drivers

No graphics drivers are currently available for the Commodore 610 (and since the machine has no graphics capabilities, chances for a graphics driver aren't really good:-).

5.2 Extended memory drivers

cbm610-ram.emd

A driver for the RAM in bank 2. Supports up to 255 pages with 256 bytes each.

5.3 Joystick drivers

The Commodore 610 is a business machine and doesn't have joystick ports. There are no drivers for the non existing ports available.

5.4 Mouse drivers

Currently no drivers available (in fact, the API for loadable mouse drivers does not exist).

5.5 RS232 device drivers

cbm610-std.ser

Driver for the 6551 ACIA chip built into the Commodore 610. Supports up to 19200 baud, hardware flow control (RTS/CTS) and interrupt driven receives. Note that because of the peculiarities of the 6551 chip transmits are not interrupt driven, and the transceiver blocks if the receiver asserts flow control because of a full buffer.
