Serial cable suggestion for NMC 0G-9354-01 / 0G-9354A-01

[skendric]

These NMC slide into the Modular PDU line.  They sport a female dB9 serial console port.  I am struggling to find a USB to male DB9 serial cable which will give me console access.

I have just purchased (4) USB-to-male-DB9 RS-232 cables, from various manufacturers ... and tried them on my Windows 10 laptop:  they all work, in the sense that my terminal emulator sees the COMx port.  But hitting 'Enter' produces no 'Username:' prompt, on either of the (2) 0G-9354A-01 which I am attempting to access (one of which is running fine, in the sense that I can reach its Web interface over the network just fine; the other of which is not responding to pings, which is why I want to jack into its serial console).

I note that I have a small stash of serial cables, for use with various APC devices (PDUs and UPSes of various flavors), which all work fine on this laptop.  So I am familiar with COM ports, 9600,n,8,1 and so forth.  I am aware that RS-232 is a rich topic, and that the cables I have purchased may not be wired suitably to provide console access to this NMC

Does anyone have a suggestion for what brand / model of serial cable I might use for this device?
