`devc-serpci`

Driver for serial PCIs

You must be root to start this driver.

Syntax:

devc-serpci [vid=vid,did=did[,pci=pci]] [options] &

Runs on:

Neutrino

Targets:

x86

Options:

-b number

The initial baud rate (default 57600).

-C size

The size of the canonical buffer in bytes (default 256).

-c clock[/divisor]

Define a custom clock rate, in hertz, and divisor for the serial port. The default (-c 1843200/16) is suitable for compatible PC serial ports.

did=did

The PCI device ID, in hexadecimal (0xXXXX).

-E

Set options to “raw” (default).

-e

Start in edited mode (default raw). Software flow control is enabled by default.

-F

Disable hardware flow control (default to hardware flow control enabled). Hardware flow control is not supported in edited mode.

-f

Enable hardware flow control (default). Hardware flow control is not supported in edited mode.

-I number

The size of the raw input buffer in bytes (default 2048).

-O number

(“Oh”) The size of the interrupt output buffer in bytes (default 2048).

pci=pci

The PCI index, in decimal (XX).

-S|s

Disable / enable software flow control. The default depends on the mode: in raw mode (-E, the default), it's disabled; in edited mode (-e), it's enabled.

The order in which you specify the -E or -e, and -S or -s options matters:

Options	Mode	Software flow control
`-e`	Edited	Enabled
`-S` `-e`	Edited	Enabled
`-e` `-S`	Edited	Disabled
`-E`	Raw	Disabled
`-s` `-E`	Raw	Disabled
`-E` `-s`	Raw	Enabled

-t number

Enable the receive FIFO and set its threshold to 1, 4, 8, or 14 characters. The default is 0 (trigger disabled).

-u number

Append number to the device name prefix (/dev/ser). The default is 1; additional devices are given increasing numbers.

-v

Increase verbosity.

vid=vid

The PCI vendor ID, in hexadecimal (0xXXXX).

Description:

The devc-serpci manager is a small serial device manager for QNX Neutrino. This driver supports 16Cxxx compatible Serial PCI cards.

The boards must use PCI I/O space for the registers, and the ports must be contiguous in memory.
