* Revision 1.4 1999/03/29 11:19:44 armin
* I/O stuff now in seperate file (eicon_io.c)
* Old ISA type cards (S,SX,SCOM,Quadro,S2M) implemented.
*
* Revision 1.3 1999/03/02 12:37:45 armin
* Added some important checks.
* Analog Modem with DSP.
* Channels will be added to Link-Level after loading firmware.
*
* Revision 1.2 1999/01/24 20:14:18 armin
* Changed and added debug stuff.
* Better data sending. (still problems with tty's flip buffer)
*
* Revision 1.1 1999/01/01 18:09:42 armin
* First checkin of new eicon driver.
* DIVA-Server BRI/PCI and PRI/PCI are supported.
* Old diehl code is obsolete.
