============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0663 02-01-91 ============================================================================= BRAVO/386SX AND KEYBOARD ERRORS When using the Bravo/386SX in various software environments, keyboard errors may occur. For example, when using IBM's Attachment 3270 emulation software, the left-hand control key does not function at all. In Lotus and SCO UNIX, the function 5 key generates erroneous characters. In Novell environments, the down arrow cursor key will act as a shift-lock or will not function at all. To resolve these problems, replace the existing keyboard with an NMB keyboard revision C (AST part number 230098-001).
