Turns on the V.42 LAPM and MNP error control protocols, if available. The
field has a blank field of 6 characters as default. The Paradyne products
use the command \N5 to enable V.42/MNP/Buffer error control while the
Intel product uses \N3 to provide similar functionality.
This V.42/MNP/Buffer mode attempts to negotiate V.42 error control with
the remote modem. If this fails, the modem changes to MNP, if this fails,
no error control is used. This field is not case sensitive. Default is upper
case.

&P1 sets a ratio of 33% make and 67% break for the United Kingdom and
Hong Kong. This field has a blank default and a 5 character long entry.
