NAME

/dev/term/ql?? − A2232 7 port serial card

SYNOPSIS

int fd;
fd = open("/dev/term/ql00", mode);

DESCRIPTION

/dev/term/ql??  are special files which, when opened, give access to a the A2232 7 port serial card device.  This device is a tty device as described in termios(7), and may be used to communicate with any RS232 standard device.  It is also a streams device and is suitable for streams functions described in streamio(7). 

The ql device driver handles XON/XOFF if requested and will always adhere to CTS/RTS flow control. 

CAVEATS

The current ql device does not handle termiox(7) ioctls. 

If the device is closed while there is pending output and CTS is low (ie, the remote side pulls RTS low or the cable is unplugged) the device will wait until it is able to complete the data transfer before returning from the close call.
