Laing <keyspan@jsl.com>) 35 Merged the current (1/31/03) Keyspan code with the current (2.4.21-pre4) 36 Linux source tree. The Linux tree lacked support for the 49WLC and 37 others. The Keyspan patches didn't work with the current kernel. 38 39 2003jan30 LPM add support for the 49WLC and MPR 40 41 Wed Apr 25 12:00:00 PST 2002 (Keyspan) 42 Started with Hugh Blemings' code dated Jan 17, 2002. All adapters 43 now supported (including QI and QW). Modified port open, port 44 close, and send setup() logic to fix various data and endpoint 45 synchronization bugs and device LED status bugs. Changed keyspan_ 46 write_room() to accurately return transmit buffer availability. 47 Changed forwardingLength from 1 to 16 for all adapters. 48 49 Fri Oct 12 16:45:00 EST 2001 50 Preliminary USA-19QI and USA-28 support (both test OK for me, YMMV) 51 52 Wed Apr 25 12:00:00 PST 2002 (Keyspan) 53 Started with Hugh Blemings' code dated Jan 17, 2002.
