Lynx 8 Port and Quad RS232 cards.
Switch: /L hexaddr, irq, range [, range] [, range]
The shorthand allowed in using port ranges with the Lynx
command, as well as the port Address and Handshake
commands, allow a multiport system to be setup by only a few
short entries in the NewCOM.SYS line in the CONFIG.SYS file.
The older notation, without ranges, where every port is
explicitly defined can still be used but is more cumbersome.
Switch: /L hexaddr, irq, p1, p2, p3, p4, p5, p6, p7, p8...
Purpose:
Set up one or more Lynx 8 port or Quad port serial cards.
The /L command has superceeded the /D command.
’hexaddr’
is address of the SISR, Shared Interrupt Status Register.
’irq’ is the interrupt line set on the Shared IRQ jumper block.
’range’
specifies the COM port. Range may be a SINGLE port OR
a RANGE of ports. Each port is a decimal number
between 1 and maxport. Multiple ranges may be specified,
if necessary, to define all the ports in use.
Range port examples:- (new method:- less typing, easy to
understand)
