Hi all,
When I tried to use Software Flow Control it's not working with uart.c
driver in kernel 2.4.2 , I send Ctrl+S character to stop the flow but the
flow is not get stopped ,
I dig something into driver and find like,
static void rs_8xx_stop(struct tty_struct *tty)
{
static void rs_8xx_start(struct tty_struct *tty)
{
these two modules are handling with the flow stop(Ctrl+S) and start(Ctrl+Q)
,
I think there is a BUG in handling the Event(SCCE) and Mask Registers (SCCM)
somewhere like
if (info->state->smc_scc_num & NUM_IS_SCC) {
sccp = &cpmp->cp_scc[idx];
sccp->scc_sccm &= ~UART_SCCM_TX;
Anybody got this problem and solved please let me know
Thanks in Advance,
KP
