They are, actually. At least to some extent.
But that requires more CPU cycles than the disk port, since the signal is
not available at bit 7 (it is in bit 6) and sending requires not just
banging a softswitch, but writing to a register.
The Dx-19 connector is going to become a problem, but at least I can still
use a "shortened" DB-25 connector.
