You will need to check which comm port you are using for the modem, what IRQ it is using, and what IRQ your printer port is using. It is common for com1 to be on irq 4, and com2 on IRQ 3, and your printer port to be on either IRQ 5, or IRQ 7. Make sure there is no conflict - if there is, you will either have to change something around, or use the printer in polled mode. (does not use an IRQ). To use the printer in polled mode, check the printing section in the handbook. Anthony
