A rather radical change for edit 190...
Some modems do not react well to parity. Also, if we are dialing through a
TCP/IP TELNET modem server, parity can be fatally misinterpreted as TELNET
negotiations. Note that at this point it is very likely that we picked up a
parity setting from the dialing directory (in the call to ludial() above).
So now we save the current parity, set it to NONE during the dialing
process, and then restore it afterwards. This should work even if the user
interrupts the DIAL command, because the DIAL module has its own interrupt
handler. BUT... if, for some reason, a dialing device actually *requires*
parity (e.g. CCITT V.25bis says that even parity should be used), this
might prevent successful dialing.
