To display current IA settings, the "show" command is recommended
instead of a "set ia" command with no options:

Options for configuring serial port-connected devices
The following command options apply to configuring serial port-connected
devices.
chartimeout=3-65535 milliseconds (applies to master or slave)
After a first byte is received, this is the time to wait for additional bytes to
either consider the message complete or to be aborted. The default is
protocol-specific, but usually 50 milliseconds. The time tags “ms,” “sec,”
and “min” can be used, so entering “5sec” results in a setting of 5000
milliseconds.
Note: the effective settings here are affected by the hardware model and
the baud rate. Setting this option to too low of a value on a busy device
could cause premature timeouts.
• Single-port products, such as Digi One IA, and Digi One IAP, can
handle very low values such as 3-5 msec.
• Multi-port products, such as the PortServer TS2 and PortServer
TS4, will not effectively handle times shorter than 10 msec.
• The large-port products, such as the PortServer TS8 and PortServer
TS16, need this value to be 75 msec or higher.
lineturndelay=0-65535 milliseconds (applies to slave only)
For slave devices that turn their serial port from transmit to receive slowly,
this parameter forces a delay between receipt of the last byte of previous
response from slave and the first byte of next request to slave. The
default is 0 (disabled). The range is 0 to 65535 milliseconds and the time
tags “ms,” “sec,” and “min” can be used.
messagetimeout=10-65535 milliseconds (applies to master only)
When messages are received from remote clients, this is the time to allow
the message to wait to be answered. This includes both the queuing and
slave response delays, and this should be set to slightly less than the
timeout of the remote client. After this time, the Digi device assumes the
remote client no longer wants a response. The default is 2500
milliseconds. The range is 10 to 65535 milliseconds and the time tags
“ms,” “sec,” and “min” can be used.
range (applies to master or slave)
The port to which the device is connected. If a range is used, then the
settings apply to the range of ports. The default is port 1.
slavetimeout=10-65535 milliseconds (applies to slave only)
After all bytes of the message have been sent to the slave device, this is
the time to wait for the first byte of a response. Note that the serial shift
times are not included within this timeout. The default is 1000
milliseconds. The range is 10 to 65535 milliseconds and the time tags
“ms,” “sec,” and “min” can be used.
