## Configures /dev/ttyS2 serial port for a US Robotics PCI modem.
##
## This startup Bourne shell script for Linux, written for a USR model 5610 PCI 
## non-winmodem, searches lines of "lspci" output until a line contains the 
## string "US Robotics", then parses from that line the IRQ and I/O port 
## assigned to that device by the PCI controller chip, then runs 
## "setserial" to initialise serial port /dev/ttyS2 (COM3, to MS-DOS people) 
## with those hardware settings.  With minimal work, the script should
## be adaptable to any other PCI non-winmodem.

DEVICE=$(lspci | grep "US Robotics" | awk '{print $1}')
