Tera Term supports it since Tera Term 4.66.

Very good. I was confused by the "Tera Term Command Line" help.
"/BAUD=<baud rate> baud rate of serial port. If the baud rate not supported by Tera Term is specified, this option is ignored. "
Is this accurate or will Tera Term ignore 125000?
ini file ; Serial port parameters ; Port number ComPort=44 ; Baud rate BaudRate=125000 ;will this work also?
Tera Term accepts 125000. If chip and device driver supports that speed, probably you can use it.
"/BAUD=<baud rate> baud rate of serial port. If the baud rate not supported by Tera Term is specified, this option is ignored. "
We will consider changing this expression of the document.
Tera Term
Request a method to select non-standard baud rates. e.g. 125k rather than 115k or 230k. FTDI driver will accept non-standard baud rates but TeraTerm does not support this feature.
