serial port configuration

OS: Linux TLE 5.0 based on Red Hat 8.
Legacy barcode printing equipment demands serial communications, 9600 baud, even parity, 7 data bits, 1 stop bit. I have found /dev/ttyS0, but how to configure the baud/E/7/1? Setserial will let me set the baud rate; change base or divisor? My C program must write to /dev/ttyS0 to run this device. No driver exists except for the standard Linux kernel serial driver. I've been using MODE.COM under MS-DOS and Windows 98; now porting to Linux. [Thank you for everything]. How do I configure the serial port?

[Repling tto my own post] A few days later I downloaded the source RPM for minicom and searched their code. The functionality I need is shown in "man termio". I could not find it because we call these things "serial ports", and Linux calls them "terminal ports". When was the last time you saw a terminal, eh? OK, so I have my answer, and I post this in case anyone else encounters this question he'll find the answer here also. Thanks.
