Fastcom®: 232/1-ISA Asynchronous Single Port RS232 Interface Adapter   $375.00

The FASTCOM: 232/1-ISA adapter supports baud rates up to 725K¹, and is one of the most advanced single-port RS232 asynchronous serial adapters in the industry. Primarily designed for commercial, industrial, and OEM applications, the FASTCOM: 232/1-ISA features both RS232C and 20MA Current Loop interfaces complete with all standard hand-shaking signals.

The advanced 16C850 UART on the FASTCOM: 232/1-ISA features full compatibility with standard 16C550 and 16C650 UARTs, but also provides extraordinary 128-byte receive and transmit FIFOs for buffering. This buffering is extremely important when working with RS232 communications within high overhead operating systems such as Windows NT and 2000. The extra-deep FIFOs prevent data loss due to overrun and dramatically improve data throughput in all applications. The advanced UARTs on the Fastcom: 232/1-ISA are capable of baud rates up to 725K¹.

The FASTCOM: 232/1-ISA is designed with a compatible mode for operation in Windows 98/2000/NT/XP, and Linux Kernel 2.4.x. The user selectable address and IRQ setting switches allow for "driverless" operation in most operating systems, i.e. uses the system serial port driver for operation. The "shared interrupt" design and user selectable address also allow the installation of multiple FASTCOM: 232/1-ISA cards in the same system.
