hylafax + 调制解调器 (USR Sportster Flash X2) + 调制解调器超时：从调制解调器读取线路

我的 Sportster Flash X2 调制解调器出现了以下问题。我们已使用 hylafax 对其进行了设置，并且可以使用一两周。但今天在接收传真时，它挂起了，没有响应。这是调制解调器上次运行时的日志

首先，我们尝试重启调制解调器，因为它通常会产生神奇的效果，但现在却没有帮助。所以我们还重启了 hylafax 甚至整个服务器。hylafax 再次启动后，它就挂在这里了

这是调制解调器的配置：

ModemType:              Class1          # use class 1 interface
ModemRate:              19200           # rate for DCE-DTE communication
ModemFlowControl:       xonxoff         # software flow control
#
ModemSetupDTRCmd:       ATS13=1&D2      # setup so DTR drop resets modem
ModemSetupDCDCmd:       AT&C1           # setup so DCD reflects carrier (or not)
ModemNoFlowCmd:         AT&H0&I0&R1     # setup modem for no flow control
ModemHardFlowCmd:       AT&H1&I0&R2     # setup modem for hardware flow control
ModemSoftFlowCmd:       AT&H2&I2&R1     # setup modem for software flow control
ModemResultCodesCmd:    ATQ0X4          # enable result codes
#
ModemMfrQueryCmd:       !USR
ModemModelQueryCmd:     ATI3
ModemRevQueryCmd:       ATI7            # XXX returns a multi-line result
#
# When AT+FCLASS=1 is issued the modem automatically switches
# to software flow control; these parameters let the fax software
# reset flow control as needed after entering Class 1.
#
Class1NFLOCmd:          AT&H0&I0&R1     # setup modem for no flow control
Class1HFLOCmd:          AT&H1&I0&R2     # setup modem for hardware flow control
Class1SFLOCmd:          ""              # modem does this automatically

#
# This should resolve "DIS/DTC received 3 times" errors:
#
Class1ResponseWaitCmd:  AT+FRS=1        # wait after sending TCF for response
#
# The remainder of this configuration is included so that the
# modem "idles" in Class 0 while not sending or receiving facsimile.
#
ModemSetupAACmd:        AT+FCLASS=0     # leave modem idling in class 0
ModemAnswerCmd:         AT+FCLASS=1A    # answer in Class 1
#
# When using AT+FRS=n we see USR modems reset themselves in the middle of sessions
# this is not good.  So, we seem to work-around that problem by not using the
# command.  Unfortunately, this isn't an ideal thing.
#
Class1SwitchingCmd:     "<delay\0727>"

我们还尝试用 ZyXEL U1496（在出现此问题之前也可以正常工作）替换 Sportster，但这个也没有响应。使用 cu 或 minicom 连接到调制解调器后，它似乎已连接，但在执行 AT+FCLASS？命令后没有响应。可能是 hylafax 出了问题，还是我遗漏了什么。我浏览了很多论坛，重新启动调制解调器后一切都应该正常工作，但在我们的例子中并非如此。

更新

好的，现在我们 100% 确定调制解调器没有问题。我们尝试将调制解调器插入 win XP 机器和不同的 linux 机器。两台调制解调器都正常工作，我可以使用基本 AT 命令查询它。问题似乎出在第一台服务器上的串行上，但日志中没有任何内容可以表明存在问题。服务器是新的 HP 360e Gen8 ProLiant，所以我希望端口没有死。我可以使用 cu -l /dev/ttyS0 连接到调制解调器，但没有 AT 命令不起作用。我也尝试过 /etc/init.d/setserial restart，但没有帮助。系统是 Debian Wheezy 7.6 内核 3.2.0-4-amd64

非常感谢您的帮助。

答案1

好的，我们终于弄清楚了问题所在。我们正在使用的 HP Proliant DL360e Gen8 将 ilo4 连接到串行端口，通过此连接，它允许远程连接到控制台。在 ilo4 bios 中禁用 ilo4 虚拟串行端口后（设置 -> 串行 CLI 状态 -> 禁用），一切都开始正常工作。

感谢您的时间
