iVIEW-100 Series user’s Manual, 2006, v2.0 ----- 100
7.6 COM port Comparison: iVIEW-100 & PC
The COM ports of iVIEW-100 are as following:
COM port Hardware
COM1 UART-0 of 80188
COM2 UART-1 of 80188
The programming of 16C550 is very different to 80188’s UART. The interrupt
handling of 80188 is also very different to PC’s 8259. Therefore if user
downloads the PC’s RS-232 application program into iVIEW-100, it will not
work.
The software driver of iVIEW-100 is an interrupt driven library, which provide 1K
QUEUE buffer for every COM port. The software is well designed & easy to use.
The software driver provides the same interface for all these 2 COM ports. User
can use these COM ports in the same way without any difficulty.
