Serial ports problem
Posted on 1998-02-06
Testing the serial ports on my computer with Dos diagnostic
programs (TuffTest, Norton Utilites, others) my serial ports
pass with flying colors (internal and external with loopback plug). But dos and windows refuse to acknowledge the existance of any device (several mice and one external modem
-all "known good") attached to the serial ports (1,2 on the board and 3,4 with a known good I?O card). It's a Tyan tomcat I with a Cyrix 86 Plus 166 processor.
