The implementation of the EASY GPRS feature has the following known limitations:
- Only one socket can be opened at a time, no multiple socket connections can be made;
- Only the first GPRS context is associated with this feature;
- The closing of a socket implies always the deactivation of the GPRS context associated;
- It is taken for granted that external processor will be able to handle at least a limited v.24 implementation: RTS,
CTS and, highly recommended, DCD lines; this because software flow control is not applicable to the feature;
- Only Mobile initiated connections can be made, it is not possible to receive incoming TCP connection requests;
- Due to the particularity of this feature, the flow control of both the directions uplink and downlink is interlocked
