Compatibility

The PyHam PE package supports the full AGWPE protocol. However, not all servers that support the AGWPE protocol include support for all facets of the protocol, and not all of them support all facets in the same way. Below are some of the documented or observed differences between the AGWPE protocol specification and the servers that PE has been tested against.

In general, where a server does not support a particular feature, the behavior is such that a request associated with that feature will be silently ignored.

The information on this page is current as of the following versions of the most popular AGWPE servers:

• Direwolf v1.7

• ldsped v1.19

• AGWPE v2013.415

• QtSoundModem 0.0.0.73

Protocol features

Note that the table below reflects only facets of the protocol that are not fully supported by all servers. All other facets are supported by all servers.

AGWPE Server Compatibility

Feature	Direwolf	ldsped	AGWPE	QtSoundModem
Application login	No	Yes	Yes	No
Port capabilities	Yes [1]	Yes	Yes	Yes
Heard stations	No	Yes [2]	Yes	No
Frames waiting on port	Yes	No	Yes	No
Monitor own frames	Yes	No	Yes	Yes
Unproto with vias	Yes	Yes	Yes	No
Non-standard connections	Yes	No	Yes	No
Incoming connections	Yes	No	Yes	Yes

Notes

[1]

Direwolf hard-codes all values for port capabilities, so the values retrieved via AGWPE will likely not match any settings specified in the Direwolf config file.

[2]

ldsped versions prior to 1.19 do not include the time data structures, only the string representation.

Additional notes

• ldsped allows a port on the host to be configured as read-only. When using a port configured in this way, functions such as monitoring will behave normally, while others such as attempting to register a callsign will silently fail.

• PyHam PE requires version 0.0.0.73 or higher of QtSoundModem due to some issues with QTSM’s AGWPE protocol implementation in earlier versions.
