- Ahh, but there are! (dvsg0223@uxa.cso.uiuc.edu) designed and had manufactured
- a card called the Golden Gate card - it sits on both the Zorro (Amiga) and
- PC bus, and provides the necessary signal translation between the two - the
- goal of the card is to be able to use IBM-PC peripherals in your Amiga, but
- have the device driver code run native on the 680X0, so this isn't a Bridge
- Board in that it doesn't have an Intel 80XX CPU on it, it just provides a
- bridge between the two busses. I've gont one of these cards and the quality
- is superb. Here's part of the writeup on the (supplied) serial device
- driver:
-
- : No mountlist entry is required to use the driver with a terminal program.
- : Simply put the driver into your "devs" directory, and change the serial
- : device in your terminal program to "ibmser.device". You do not need to have
- : "binddrivers" or any other mounting program. The AmigaDOS operating system
- : will automatically mount the driver when it is first used.
- :
- : The driver supports up to four units, numbered 0 through 3. These
- : correspond to the IBM serial devices COM1 through COM4. You must set up the
- : dipswitches/jumpers on your modem or multi I/O card to make the serial port
- : COM number you want to use match the unit you specify with your serial
- : device.
- :
- : The driver will automatically select FIFO buffering if it senses a newer
- : series 16C550-compatible UART chip in the IBM card. Otherwise, it will stay
- : with normal 16C450 compatibility.
- :
- : If you want to access the new serial ports from the CLI, you can experiment
- : with creating a mountlist entry, listing "ibmser.device" under the device
- : heading.
- :
- : I have been using this driver with a v.32 IBM-type internal modem on my
- : A3000 at 38400 DTE baud rate without any problems.
