question about drivers/serial/jsm/jsm_neo.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The file drivers/serial/jsm/jsm_neo.c contains the following code in the 
function neo_parse_modem:

	jsm_printk(MSIGS, INFO, &ch->ch_bd->pci_dev,
			"Port: %d DTR: %d RTS: %d CTS: %d DSR: %d " "RI: %d CD: %d\n",
		ch->ch_portnum,
		!!((ch->ch_mistat | ch->ch_mostat) & UART_MCR_DTR),
		!!((ch->ch_mistat | ch->ch_mostat) & UART_MCR_RTS),
		!!((ch->ch_mistat | ch->ch_mostat) & UART_MSR_CTS),
		!!((ch->ch_mistat | ch->ch_mostat) & UART_MSR_DSR),
		!!((ch->ch_mistat | ch->ch_mostat) & UART_MSR_RI),
		!!((ch->ch_mistat | ch->ch_mostat) & UART_MSR_DCD));

The whole function uses constants with the name "UART_MSR_..." except for 
the first two lines of this print statement, which uses constants with the 
name "UART_MCR_...".  Furthermore, UART_MCR_DTR is equivalent to 
UART_MSR_DCTS and UART_MCR_RTS is equivalent to UART_MSR_DDSR.  Is this 
intentional?

thanks,
julia
