"Max H. Parke" has modified the commadpt driver to work for APL\360. Here is Max's README regarding his APL\360 mods: 1. Here is the APL conf that I used 1750 APLDEV (X'00',X'03'),TYPE=AMBIG,SAD=NOP 1800 APLDEV (X'40',X'43'),TYPE=1052 1850 APLDEV (X'80',X'83'),TYPE=TS41,SAD=NOP 1900 APLDEV (X'C0',X'C3'),TYPE=1052 With TYPE=AMBIG your telnet connection should close after using )OFF: "off 002 23.55.39 12/03/84 u01 connected 0.01.05 to date 0.23.08 cpu time 0.00.00 to date 0.00.00 Connection closed by foreign host. 2.
