The LaserWriter IINT/NTX Manual, in the section that tells how to use the
LaserWriter II with MS-DOS applications (page 113) says to use the DOS MODE
command to set the COM1: port to 7-bit word length. On page 120, the manual
states that the default serial word length is 7 data bits.
These are errors. The COM1: port word length must be set to 8 bits, and the
default serial word length is also 8 bits.
