3.9 Limitations

1. Performance is dependent on the computer system in which the software is used. In

general, more powerful systems and systems with lighter process loads can accommodate

the highest cumulative data throughput.

2. DMA serial ports are used only as standard interrupt-driven ports.

3. The OS/2 and DOS session MODE commands are not capable of working with ports

COM10 through COM32.

4. The interrupt status register support of Quatech ISA and MCA adapters does not permit

these adapters to share their IRQ level with any other device. Quatech PCI adapters can

share their IRQ level with any other device whose drivers support shared interrupts.
