APCUPSD：无法在任何串行端口上找到 UPS

我在一台有 2 个物理串行端口的计算机上安装了 APCUPSD。UPS 是带有串行端口的 APC SUA1000。我将 APC 智能串行电缆连接到 COM1，将 COM2 连接到另一台计算机。

ls -l /dev/ttyS*

报告 ttyS0 一直到 ttyS31。我几乎尝试了每一个端口，但都无济于事。

/etc/default/apcupsd

运行apcaccess也失败，出现“连接被拒绝”错误。是的，我已编辑/etc/hosts文件以更正 localhost... 问题。

我被难住了。有人能帮忙吗？

操作系统：Ubuntu Server 16.04.3 i386。

答案1

提醒自己：不要指望 RS232 电缆可以与 RS422 端口兼容。

通过使用 RS232 端口解决。
