Re: [digitalradio] Re: High speed packet
Going too fast on a serial port is not always a bonus. If there are errors, it is another source of retries, without even reaching the air. Go only as fast as it makes sense with very few or no errors. YMMV.

[digitalradio] Re: High speed packet
Have you tried Outpost or Winpack. Outpost is a newer program and Winpack has some age. The AGWpe software may be needed to bridge these programs. I will be using a uTNT, in kiss, with AGWpe and Winpack some. 73, Lee --- In digitalradio@yahoogroups.com, Ross [EMAIL PROTECTED] wrote: I am looking for a packet program, which I can use to operate my Symek TNC3S at 57600 but which has the kiss mode.
