Synchronous RS-232 serial connectivity is an
appropriate choice when rigorous security and intensive data integrity protocols
are required for high-speed serial communication. It is the communication method
of choice for a wide variety of military and commercial systems such as
satellite monitoring, radar control, GPS systems, flight recorder data
transfers, and HF (High Frequency) e-mail systems to name a few. Quatech's single port RS-232
synchronous serial PCI board supports asynchronous data formats as well as
byte-oriented synchronous protocols such as BiSync, and bit-oriented synchronous
protocols such as HDLC and SDLC. The card's robust design provides 1024-byte
transmit and receive FIFOs, and a SCC with advanced internal functions including
on-chip baud rate generators and digital phase-lock loop (DPLL) for recovering
data clocking from received data streams.
Quatech's frame-level HDLC and Bisync
driver, SyncDrive, is included for Windows 95/98/Me and OS/2. For Windows
2000/XP, SyncDrive Plus, a bit-synchronous SDLC/HDLC driver is also included.
Both SyncDrive packages are not application programs themselves, but provide C
callable routines and C data structures designed to aid users in the development
of their own application software.
