If You Are Using MS-DOS
Because there is no communications software built in to MS-DOS, you
must install and run a third-party communications software package to
operate your Courier V.Everything.
You must choose the COM port to which your Courier V.Everything is
attached in whatever communications software package you are using.
For instructions about how to set up your MS-DOS communications
software package, see the software documentation or visit the U.S.
Robotics Totalservice web site at http://totalservice.usr.com.
For Internal Couriers Only
You must choose the COM port, IRQ, and the I/O address within the
communications software that you use. These are the standard I/O
address and IRQ settings for each COM port:
COM Port I/O Address IRQ
COM1 03F8 IRQ4
COM2 02F8 IRQ3
COM3 03E8 IRQ4
COM4 02E8 IRQ3
