No, I took the modem out completely, shutdown and restarted cold.  I
checked /var/log/messages and the dmesg log, but there were no entries with
irq 3 except the sio1 device, which as I understand is as it should be.
The boot messages display:

	sio1 at 0x2f8-0x2ff irq on isa
	sio1: type 16550A

The AT commands still exhibit the same behavior, where I have to press the
enter key to display the modem return codes one byte at a time to screen. 
Any additional help is greatly appreciated!
