From: Russell King Russell was unable to correctly migrate this driver to the new modem-control-signal API because TIOCMBIS/TIOCMBIC do not control only the DTR signal, but also the RTS, OUT1 and OUT2 signals, or even maybe nothing at all. Plus, these IOCTLs are no longer passed down to the driver. Instead, drivers should implement tiocmget and tiocmset driver methods. so mark it as broken so as to not break allmodconfig/allyesconfig. --- drivers/net/wan/Kconfig | 2 +- 1 files changed, 1 insertion(+), 1 deletion(-) diff -puN drivers/net/wan/Kconfig~pc300_tty-is-broken drivers/net/wan/Kconfig --- 25/drivers/net/wan/Kconfig~pc300_tty-is-broken 2004-01-18 16:19:28.000000000 -0800 +++ 25-akpm/drivers/net/wan/Kconfig 2004-01-18 16:19:28.000000000 -0800 @@ -382,7 +382,7 @@ config PC300 config PC300_MLPPP bool "Cyclades-PC300 MLPPP support" - depends on PC300 && PPP_MULTILINK && PPP_SYNC_TTY && HDLC_PPP + depends on PC300 && PPP_MULTILINK && PPP_SYNC_TTY && HDLC_PPP && BROKEN help Say 'Y' to this option if you are planning to use Multilink PPP over the PC300 synchronous communication boards. _
