Hugh,
I had the same problem. I had just purchased and Emerson IBM compatible
and couldn't find any information in the manual - so - I called the tech.
support number and here's what they told me:
Serial 9-pin connector for Emerson:
PIN No. Function
^^^^^^^^^ ^^^^^^^^^^^
1 Data Carrier Detect
2 Receive Data
3 Transmit Data
4 Data Terminal Ready
5 Ground
6 Data Set Ready
7 Ready To Send
8 Clear To Send
9 Ring Indicator
Hope this is correct and helps you out. I haven't made up my cables yet,
but this is what the tech support group gave me.
Looking forward to see if anyone else has the same pinout.
