Keywords: com configure Message-ID: <1o2htt$lgo@wzv.win.tue.nl> Date: 15 Mar 93 18:29:17 GMT References: <jl.732052568@argon> Organization: Eindhoven University of Technology, The Netherlands Lines: 21 NNTP-Posting-Host: gvr.win.tue.nl Could you please post what you have in your config file? Just saying that you did everything right doesn't give much info. Besides, I have a system up and running with 3 comports one of which is an internal modem and one using irq5. What might be wrong is that you don't use the proper IO ports. In isa.h only the ports for COM1 and 2 are present. Mine contains: #define IO_COM4 0x2e8 /* COM4 i/o address */ #define IO_COM2 0x2f8 /* COM2 i/o address */ #define IO_COM3 0x3e8 /* COM3 i/o address */ #define IO_COM1 0x3f8 /* COM1 i/o address */ So you should jumper your com2 (the third port) to behave like COM3 (grr....how confusing) and rewire irq3 to irq5. -Guido -- Guido van Rooij | Internet: guido@gvr.win.tue.nl Bisschopsmolen 16 | Phone: ++31.40.461433 5612 DS Eindhoven | ((12+144+20)+3*sqrt(4))/7 The Netherlands | +(5*11)=9^2+0
