sys/i386/isa/ic cd1400.h
sys/i386/isa cy.c
Log:
Implemented sending of BREAKs. This is quite complicated because the
hardware is interrupt-driven to a fault and sending a BREAK requires
mode switching. Always running in the BREAK-capable mode as in PR 8318
would double the overhead for sending \0's.
