That may depend on which version of asyn you are using.  The upcoming R4-27 release contains the following in the release notes:

*******************************************
Fix to automatically prefix COM port names larger than COM9 (e.g. COM10, COM11, etc.) with "\.\". This is needed for all ports except COM1-COM9. Thanks to Freddie      Akeroyd for this fix.
*******************************************

If you are running the master branch from github you already have this fix.  If not then I think you can work around the problem by using the full path name to the port when you open it, i.e. \\.\COM10.

Hi Peter,





I'm using asyn/stream with ports 10 and 11 without troubles.





HTH,

Hi,
 
The devices (pump controllers) are named TT01, TT02, TT03, TT04, NT07 and NT10, respectively.
These were attached to COM1, COM2, COM3, COM4, COM7 and COM10 (only in the interests of matching the number scheme, above).
 
When I installed the software, the first five worked perfectly.
But the last one was unable to connect.
 
On a hunch, we re-mapped the last comport to COM8:, in the operating system.
Now all 6 work perfectly.
 
I wondered if there is a single-numeric-digit constraint, on the serial port number?
 
Thanks,
 
Peter.
