Escaped com port opens as network device

[mdblack98]

Setting rig as serial, with a port of (e.g.) \.\COM3 to be able to
access high numbered Windows COM ports, hamlib tries to open them as
network - tracing it

we set

rig.state->rigport.type.rig = RIG_PORT_SERIAL, and then

17:55:11.214 Hamlib: rig_init called
17:55:11.214 Hamlib: ft1000mp_init: called
17:57:35.976 Hamlib: rig_open called
17:57:35.976 Hamlib: rig_open: using network address \.\COM3
17:57:35.976 Hamlib: port_open called
17:57:35.976 Hamlib: network_open called
17:57:35.976 Hamlib: network_open version 1.0
17:57:35.991 Hamlib: network_open: hoststr=\.\COM3, portstr=
17:57:36.132 Hamlib: network_open: cannot get host "\.\COM3": The
operation completed successfully.
