In the T20e, AT commands are used both for:

•controlling the data communication between the PC and the remote service. This requires the Mobile Office DI 28 infrared modem (optional accessory).

•configuring and requesting settings and behaviours in the phone, from a connected PC or PDA. This requires the Mobile Office DI 28 infrared modem (optional accessory), or the RS-232 cable DRS-10 (optional accessory).
