Adding or removing other hardware may change the assignment of I/O addresses and IRQs. Clock Modes The COMM+232.PCI employs a unique clocking option that allows the end user to select from divide by 4 and divide by 1 clocking modes. These modes are selected at Headers E1 and E2. - Page 7 If your communications package allows the use of Baud rate divisors, choose the appropriate divisor from the following table: For this Data Rate Choose this Divisor 1200 bps 2400 bps 4800 bps 9600 bps 19.2K bps 38.4K bps 57.6K bps 115.2K bps 230.4K bps 460.8K bps © Sealevel Systems, Inc. 7202 Manual | SL9059 7/2021...

Page 10: Technical Description
IRQ (short for Interrupt ReQuest). In these early days of PC’s Sealevel Systems decided that the ability to share IRQs was an important feature for any add-in I/O card. Consider that in the IBM XT the available IRQs were IRQ0 through IRQ7. Of these interrupts only IRQ2-5 and IRQ7 were actually available for use. - Page 11 The ISP is at Base+7 on each port (Example: Base = 280 Hex, Status Port = 287, 28F… etc.). The COMM+232.PCI will allow any one of the available locations to be read to obtain the value in the status register. Both status ports on the COMM+232.PCI are identical, so any one can be read.
