Lines: 24 Message-ID: <4hfr5a$80u@bluesprings.in-brb.de> NNTP-Posting-Host: bluesprings.in-brb.de X-Newsreader: TIN [UNIX 1.3 950824BETA PL0] Hi I have a Vision Turbo 4COM (Multiserial, Highspeedcard). If i run this card in "polling mode" on one IRQ and 460800 bps and with 50%CPU-time from a 486/100 to handle the zmodem-receive, i've got 36kByte/s and many sio overflows. But i can switch the card with a jumper to use a interrupt-vector-register. That must disable the sio-overflows and CPU-usage. To configure the kernel for using a "master-port" is, that i say to my kernel, that the vector-register is exactly 7 bits behind the beginning of the last port - right? (com_scr) But this card has the last port on 0x118-0x11f and the vector-register is on 0x140-0x147. How can i patch sio.c to got the register right? I've played around with some defines, but nothing happens - because i dont how, how this code works. :) I hope that somebody help me to setup the card correctly - in 2 months there will come out a new 8-Port-card with the speed of this 4-Port-card. And i think that they include a documentation, how to setup with freebsd. Lars.
