MeSsy-DOS recognizes four specific port addresses for serial : ports in order: 0x3F8 0x2F8 0x3E8 0x2E8 : However, MacroSquish in their (?)wisdom still left only the two IRQ lines : specifically allocated to COM ports. Modern serial cards typically let you : use IRQ 5, and some add IRQ 2 to the possibilities as well. FreeBSD lets : you configure all four (use the -c option at the boot: prompt, then type V : or visual at the config> prompt). The serial ports are near the bottom of : the expanded list. The '-c' option. Interesting, I didn't know that. I was going near crazy at the time when I was trying to get FreeBSD to recognize my then internal modem. Although I still feel better knowing the mouse & modem are assigned to sio0 & sio1. My situation could have also been system board specific. : > : > You'll have to move your modem to sio1 (com2), and most likely : > disable com2 on your controller card, as well as setting any modem : > jumpers/switches that apply to com ports. : As long as both Kermit and FreeBSD can agree on where and how to find your : modem and its IRQ, they will both work. : > : > Provided your setup is not any complicated, getting FreeBSD to : > recognize your modem is a simple process. : > : NB: If you have recompiled your kernel and removed some of the SIO entries, : you'll have to go back and put them back in again.
