As I needed support for DTR/DSR hardware handshake to communicate with a serial printer (and the "wire RTS/CTS to DTR/DSR" tip from the serial-HOWTO works fine for a demo, but is not applicable for a few thousand POS terminals *gg*), I implemented this functionality.
Yilch. This is specialized enough that I'd much rather this *not* go into the kernel. Next thing we know, someone will want a DTR/CD handshaking mechanism, etc.,etc.
This should probably be a private kernel patch, or (much more strongly suggested) that you just get specially wired RS-232 cables. This is in fact a very standard thing to do, and you can order cables from Black Box or some other company specializing selling cables which connect crufty legacy hardware.
