+ * $Log: eicon_idi.c,v $
+ * Revision 1.9 1999/03/29 11:19:42 armin
+ * I/O stuff now in seperate file (eicon_io.c)
+ * Old ISA type cards (S,SX,SCOM,Quadro,S2M) implemented.
+ *
+ * Revision 1.8 1999/03/02 12:37:43 armin
+ * Added some important checks.
+ * Analog Modem with DSP.
+ * Channels will be added to Link-Level after loading firmware.
+ *
+ * Revision 1.7 1999/02/03 18:34:35 armin
+ * Channel selection for outgoing calls w/o CHI.
+ * Added channel # in debug messages.
+ * L2 Transparent should work with 800 byte/packet now.
+ *
+ * Revision 1.6 1999/01/26 07:18:59 armin
+ * Bug with wrong added CPN fixed.
+ *
+ * Revision 1.5 1999/01/24 20:14:11 armin
+ * Changed and added debug stuff.
+ * Better data sending. (still problems with tty's flip buffer)
+ *
+ * Revision 1.4 1999/01/10 18:46:05 armin
+ * Bug with wrong values in HLC fixed.
+ * Bytes to send are counted and limited now.
+ *
+ * Revision 1.3 1999/01/05 14:49:34 armin
+ * Added experimental usage of full BC and HLC for
+ * speech, 3.1kHz audio, fax gr.2/3
+ *
+ * Revision 1.2 1999/01/04 13:19:29 armin
+ * Channel status with listen-request wrong - fixed.
+ *
+ * Revision 1.1 1999/01/01 18:09:41 armin
+ * First checkin of new eicon driver.
+ * DIVA-Server BRI/PCI and PRI/PCI are supported.
+ * Old diehl code is obsolete.
