Hi! First of all i wanna thanks to every one in the list that help me to make the TCM 3105 work. Al last, today i could stablish the 1st TCP/IP connection over packet radio. Thanks to all!! But after testing the transfer rate i found that i'm having a 250 bps speed!!! this is far to the 1200 bps i was expecting!! :) I using a TCM 3105 (on both points of the connection), an Icom ic-746 and a handy adi-210 (we'are using the 2m band). The distance between stations is about 1 mile and the incoming signals in both stations were good. One station has kernel 2.0.36 and the other 2.2.7 (both RH) with ax25-utils 2.1.42a. In both kernels are compiled the Baycom fullduplex ser12 driver. I hope this information is enougth to figure out what could be happening that make the connections so slow... Thanks in advance.
