Not setting the baud rate and not writing status registers is unlikely to produce working results. This 9600 must be the default setting being applied. > Jul 29 05:20:07 NICK2 kernel: drivers/usb/serial/io_edgeport.c: > SendCmdWriteUartReg - Not writing to MCR Register > Jul 29 05:20:07 NICK2 kernel: drivers/usb/serial/io_edgeport.c: MCR - > write to send_cmd_write_uart_register register 0x0b > Jul 29 05:20:07 NICK2 kernel: drivers/usb/serial/io_edgeport.c: > SendCmdWriteUartReg - Not writing to MCR Register > Jul 29 05:20:07 NICK2 kernel: drivers/usb/serial/io_edgeport.c: > change_port_settings - baud rate = 2400 > Jul 29 05:20:07 NICK2 kernel: drivers/usb/serial/io_edgeport.c: > SendCmdWriteBaudRate - NOT Setting baud rate for port = 0, baud = 2400 Here's apcupsd trying to set 2400 baud. Please try the attached patch (against 2.6.22.1). This will allow writing to the baud rate and MCR/LCR registers on non-EPIC adapters. I suspect the previous code was a copy-paste error. --Adam
