- Here it is boys and girls, a kludgy driver to use your buffered
- uart. A couple of caveats, the command line IS CASE SENSETIVE.
- I reccomend you just cut and paste from the following examples to
- put it in your config.sys. It's a plug in replacement for com16450.sys,
- so if you already use that, then just make a minor edit to the filename
- in your device statement. here's my config.sys snippet for a 16450 on
- com1, and a 16550 on com2:-
-
- DEVICE=c:\mydll\com16450.sys COM1 3F8 4
- DEVICE=c:\mydll\com16550.sys COM2 2F8 3
-
- Both device drivers are included in this care package. As you will see,
- there are some command line options. First is the device name. It MUST
- start with COM, and be followed by a single digit, ie COMx. Case is
- sensative. the entire command line is case sensative. The second item
- on the command line is the base port for the device (in hex), and the
- final is parameter is the irq to use. You cannot share irq lines at
- this time. The above sample shows the standard configuration for com1
- and com2. You can install as many instances as you have serial ports
- and irq lines to spare. I currently have 4 instances installed in my
- config.sys to handle 4 com ports.
-
- One final note about com16450.sys. It's not buffer aware, so if you
- install it on a serial port with a 16550 in there, it's liable to trap
- unless you re-init the system from a power down. Since there is a
- separate driver for the 16450 and 16550, I'm not going to fix that. It
- does turn into a minor performance issue. I dont particularily like to
- add 2 more instructions to an already bloated interrupt handler.
-
- If you have comments, send netmail to 1:153/905. I will listen to
- constructive comments only, and also to bug reports. I have a policy
- around here of
-
- Yelling >> NULL
-
- So if you have problems, please describe them in detail. If you start
- yelling about a broken drive or some such, and want to blame my driver
- I just wont listen. If you approach me reasonably, I'll do everything
- I can to help rectify your problems. I too want this driver to be reliable
- cuz it's running on my system as well.
-
- With that out of the way, have fun with the new toy. I sure am.
