Software Configuration
COM ports 5,6,7 and 8 are defined, with an i/o address
range that begins at 0140h and all subsequent ports have an i/o
address that is 8 higher than the previous. i.e. if COM5 has an
address of 0140h, then COM6 will have an address of 0148h,
COM7 an address of 0150h etc.
PCI Lynx 8 Port RS232 Users: /A5-12,0140
SISR, IRQ, Range.
/L 0104,11,5-8
0104h is the i/o address SISR, 11 is the IRQ and since the
COM port range is COM5 - COM8 range is entered as 5-8.
PCI Lynx 8 Port RS232 Users: /L 0104,11,5-12
Number Buffer.
/B8
8 buffers are defined, though only four ports are in use -
this is because buffers in DOS are assigned in a sequential order
from COM1. Since the PCI Quad RS232 has been assigned COM
port values of 5 to 8, all preceding COM ports, must have buffers
assigned to them also.
PCI Lynx 8 Port RS232 Users: /B12
Buffer Size.
/S512
Buffer size set to 512 bytes.
Hardware Handshaking.
/H,4
Type 4, 3 Wire Handshake selected for all ports.
