Tapan, Ryan, As Ryan owns another 537 hardware which looked to be supported by the original Intel's driver and the symptoms are identical (8250_pci allocating the 537 uart ports), I'll check with Ryan whether efax does correctly answer or not. If Ryan's 537 board still does NOT correctly answer on efax sollicitation despite my latest driver downloadable at http://vouters.dyndns.org:8080/Intel/ this will mean there is an interaction on setting the UART hardware bits on the 537 board by either the Linux kernel provided 8250_pci.c or 8250.c code. This would mean the tty_unregister_driver call I added to my 537 code would cause the 8250_pci driver (aka serial) to NOT cleanly reset the hardware to a correct known state. And the effect of it on efax or stty sollicitations would be the 537 driver to output the following message in /var/log/messages: " Can't initialize modem h/w " Yours sincerely, - http://vouters.dyndns.org:8080/ Philippe Vouters (Fontainebleau/France)
