8 Misc. notes for RISCom/8 serial driver, in no particular order :)
9
10 1) This driver can support up to 4 boards at time.
11 Use string "riscom8=0xXXX,0xXXX,0xXXX,0xXXX" at LILO prompt, for
12 setting I/O base addresses for boards. If you compile driver
13 as module use insmod options "iobase=0xXXX iobase1=0xXXX iobase2=..."
14
15 2) The driver partially supports famous 'setserial' program, you can use almost
16 any of its options, excluding port & irq settings.
17
18 3) There are some misc. defines at the beginning of riscom8.c, please read the
19 comments and try to change some of them in case of problems.
20
21 4) I consider the current state of the driver as BETA.
22 If you REALLY think you found a bug, send me e-mail, I hope I'll
23 fix it. For any other problems please ask support@sdlcomm.com.
24
25 5) SDL Communications WWW page is http://www.sdlcomm.com.
26
27 6) You can use the script at the end of this file to create RISCom/8 devices.
28
29 7) Minor numbers for first board are 0-7, for second 8-15, etc.
