How to adjust Baud rate in rpVT

rpVT's COMM mode supports baudrates from 115200 down to 110 baud. However, it's not trivial to find the keyboard commands to change them.
First, the baudrate change commands <u>are</u> present in rpVT. Take a look at rpVT's Help system:
click on rpVT's menu Help topic "Keyboard - F1" (or type Shift-Ctrl-F1)
in the yellow Help window, in the middle of the right pane you find:
" < - decrement Baud rate "
" > - increment Baud rate "

Problem

Unfortunately there's no Menu command line to increment or decrement the Comm Baudrate. So you have to use the keyboard equivalents. But a quick try typing "<" and ">" shows that baudrate won't change.

Solution

rpVT obviously listens to the keyboard in a special manner, see file "SCKeys.kbd" in the rpVT folder.

On a German keyboard, neither the "US keyboard" nor the "German keyboard" part does fit exactly, at least here.
You can verify the keyboard codes by invoking rpVT's Search function (either click on Tool - Search, or in ZTree press Sh-Ctrl-S and give rpVT the focus). You'll find that Shift-Comma is the "<" and Shift-Dot is the ">".

As usual, rpVT commands have to be entered together with Shift-Ctrl. So to "Decrement baudrate" you have to type "Sh-Ctrl-Comma". This obviously addresses the "<" which is assigned to the Shift-"," (Comma) key.

Step by Step Summary

To change rpVT baudrate, make sure the following steps apply:
Make sure that you invoke rpVT with command line switch "/caX". X can be any digit(s) according to the COMx slots availabe on your Windows machine. See rpVT menu Help topic "COMports" for details / availability.

Within ZTree (Z) or rpVT (R), type Sh-Ctrl-F7 to switch R to COMM mode.
In R's top line, the status changes from "view" to "ComX 115200b" (blue-coloured here).

Make sure that the Comm port number is not empty (as in "Com ?115200b"). If it is empty, the corresponding COMx port is not available for Windows.
To change Comm port number, use R's F6 command, see rpVT menu, Tool, "Set COMport - F6"

To decrease baudrade, type "Shift-Ctrl-Comma".
To increase baudrade, type "Shift-Ctrl-Dot" respective.
Both are available from R or Z.
