The server is definitely not communicating with the modem.

I am using ttyS01 (com2/irq3). I have SME 5.0 loaded at the moment since it 
has the Mitel modem test utility. The test fails of course.

The Award BIOS shows two ports enabled:
. serial port 1 - 3F8/irq4
. serial port 2 - 2F8/irq3

dmesg shows:
. Serial driver version 4.27 with MANY_PORTS MULTIPORT SHARE_IRQ enabled
. ttys00 at 0x03F8 (irq = 4) is a 16550A
. ttys01 at 0x02F8 (irq = 3) is a 16550A

The 16550A UART should run at 115K with no problem, but I have it set lower 
in Minicom. SME set speed at 115K in /etc/diald.conf.
