Number Buffers.
Switch: /B buffs
Purpose:
Set number of pairs of buffers to be allocated.
buffs
is a decimal number in the range 1-maxport and is the
number of buffers to allocate. Each interrupt driven port
needs its own buffer so this also sets the maximum number
of ports that can be used in interrupt mode.
Always ensure that there is one for each port in use.
NewCOM reserves space for the buffers from main memory
when the machine is booted. Each port whose address is known
at boot time either by the being recognised by the ROM BIOS
or whose address is set in the config.sys file have a buffer
allocated to them when NewCOM.sys loads, provided sufficient
are defined using the /B command.
For example
/B 9 reserves 9 buffers, one for the built in COM1 port and one
each for the 8 ports on the Lynx card.
For example
/B 4 reserves space for four pairs of buffers, enough for four
serial ports.
The default is six pairs. The buffer allocated contains an equal
amount of room for both the incoming data and the out going
data.
