We offer two serial communication drivers:
RS485 is a server with its own interrupt handler. It controls the RS-485 transmit driver. It can use any interrupt, including the upper ones like 10 and 12. It support the faster baud rates as well as the FIFO buffering mode of the 16550 chip. The driver returns a specified number of characters or a string terminated by a specified character. Otherwise, it times out and returns an error code after a delay specified in ms. The full-duplex RS-422 mode is also supported.
RS232 is a server with its own interrupt handler. It can use any interrupt, including the upper ones like 10 and 12. It support the faster baud rates as well as the FIFO buffering mode of the 16550 chip. The driver returns a specified number of characters or a string terminated by a specified character. The driver supports full duplex communications.
HIDEV.SLIB is a shared library that remaps INT 4 into the INT 15 vector. It is used to allow the DEV administrator to use the interrupts above 7 for serial devices.
