Not for 115200 however. In fact the net5501 supports that speed: set ConSpeed=115200 show ConSpeed = 115200 Result: r...@hibernia:~# cu -l /dev/ttyUSB0 -s 115200 Connected. POST: 012345689bcefghips1234ajklnopqr,,,tvwxy Providing support for an undocumented serial transfer rate (or not documenting a supported rate - I looked into both the manual and the changelog, but I couldn't find it mentioned anywhere) is surely an effective way to confuse users. > and the problem could therefore be delegated to > the terminal configuration.

Hard to imagine how this could happen involuntarily, possibly through thoughtless automatism. Maybe a fine excuse to finally update/create the net5501 doc. By the way, assuming that the UART supports 8 speeds (probably), if 6 speeds are this one is also supported, which is the 8th one? I hope I'm not missing something fundamental here..
