There may be a limit in the operating system, but not in the ASYN serial port driver (you are talking about ASYN, right?).  There’s no check at all on the serial port name -- the drvAsynSerialPortConfigure serial line name argument is passed directly to the ‘open’ system call.

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?
