Two auto repeat modes are available and are set via the same command:
Resend Key Mode
Key Up/Down Mode
Yes
When the key code associated with key ’P’ (0x50) is pressed, the release
code is ’p’ (0x70). In RS-232 polled mode or via the I
Down / Key Up” codes are used; however, the user should be careful of
timing details. If the poll rate is slower than the simulated auto-repeat it
is possible that polling for a key up code will be delayed long enough
for an unwanted key repeat to be generated.
This command turns auto repeat mode off. See Set Auto Repeat Mode.

a PC. In this mode, when a key is held down, the key code is
transmitted immediately followed by a 1/2 second delay. After
this delay, key codes will be sent via the RS-232 interface at a rate
of about 5 codes per second. This mode has no effect if polling or
if using the I
rameters of the “Resend Key Code” mode are unacceptable or if
the unit is being operated in polled mode. The host system detects
the press of a key and simulates an auto repeat inside the host sys-
tem until the key release is detected. In this mode, when a key is
held down, the key code is transmitted immediately and no other
codes will be sent until the key is released. On the release of the
key, the key release code transmitted will be a value equal to the
key down code plus 20 hex.
