Epson 10020 - Manual (Page 27)

The Setup program on your Reference diskette lets you define
the baud rate, parity, data length, and number of stop bits for a
primary and a secondary serial port. See “Running the Setup
Program” in Appendix A for instructions.
To redirect the printer data you can use either the MS-DOS
MODE command or the Epson MENU utility. (MENU
provides an easy way to use MODE. For instructions, see the
description of the Mode Settings option of the MENU program
in your MS-DOS Reference Manual.)
