According to the documentation to use a USB serial port adapter for
output on a port other than 03/04 I can use the following SIMH commands:

ATTACH TTOX Line=0,\dev\USBTTY0

This would put TTOX at 41 assuming the default TTOX ports

But how do I set it for 110 baud, 8-P-2?  Does it use the same syntax as
the set console serial=/dev/USBTTY0:110,8P2?

Will I also need to use the set ttox 8b,nolog?  Will it default to not
UC if I don't specify UC.

The set ttox command does not support setting stop bits or baud rate
that I can find.

My goal is to use my ASR33 to punch binary tapes and text tapes as an
output only device and not on the console.

Thank you David Gesswein for getting me this far.

Thank you,
