I have read the FAQ and I have seen this conversation before. The problem with multiple and simultaneous use of more than two com ports is obviously because only IRQ3 and IRQ4 are supported by most devices. However, some devices allow you to set the IRQ. I have a modem that allows this. So...I set my modem to IRQ2 and changed the system.ini file appropriately. But Windows crashes (i.e. exits to DOS) as soon as I open that communications port. So, MY QUESTION !!! If I can set the IRQ for a particular device, Can I Get Windows to Support more than TWO com ports simultaneously ??? Or do I have to wait for 3.1 Thanks...Regards |(8> --- Robert

You can do this on a EISA or MCA machine, so the doco says. I think SYSINI.TXT (or SYSINI2) has some stuff on this and there was also some stuff in Interrupt Sharing on OnLine. Basically, forget it. I think it is hackable. I have done it in DOS on non-MCA machines but you have to hack your coms cards IRQ output line - not pretty. I did it on a multi-port card so it was easy to set up. But basically no, unless you are one of the four people with an EISA or MCA machine. +-------------------+-----------------------------------------+ | Glenn Wallace | Net: drift@qut.edu.au | | Drift Project | Fone: +61 7 837-7126 Fax: +61 7 221-0173| | Telecom Australia | Snail: 11th Flr 144 Edward St., | +-------------------+ Brisbane, Q4000 Australia | | | | Disclaimer - The opinions expressed must be my own, because | | Telecom is a statuatory authority and as such, | | is not capable of having opinions. | +-------------------------------------------------------------+
