Does anyone know if the Phoenix BIOS immediately enables interrupts at power-on? I have an AT&T 6386E/33 with a serial cable on COM2 that goes to a 3B2/400 serial port that has a uugetty running on it--that is, it is a bidirectional port driver. When I cold boot the 6386, it runs at a tiny fraction of its normal speed. Eg., the letters "Phoenix" appear on the screen one at a time with a 1-2 second pause between them! It was suggested that if the interrupts are not disabled and the BIOS sends anything out the serial port, the 3B2 will respond by sending "login" out the port. This becomes a nearly deadly embrace! I should point out that the 386 with the AMI BIOS does not do this. Thanks, Pete -- Prof. Peter J.
