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.

  JNOS is probably the most actively maintained version of NET which

  it can be run under either Windows or Linux.  JNOS has KISS as one of
  its historic interface methods.  As long as you have a more modern
  serial communications chip in the computer you're using
  (16550-compatible) you should be able to configure it to have
  adequate communications with the TNC at either 57.6kbps or 115.5kbps,
  if the TNC supports it.

  The SV2AGW family of programs may also support that fast serial data
  rate - I don't have an easy way to check where I'm entering this
  email.  The AGW Packet Engine (AGWPE) definitly also understands how
  to do KISS.  My home Airmail station is using a shim to talk to
  AGWPE, which is talking to an AEA PK-96 using KISS, which is then
  interfaced with the radio.

  Perhaps I've not been watching the list carefully - what over-the-air
  data rate are you using that makes performing serial communications
  at 57.6kbps an advantage?  Unless you're sending quite large AX.25
  packets (1k or 2k) on a radio link at 38.4kbps, there's probably not
  much performance advantage to going that fast.  And if your on-air
  data rate IS that fast, congratulations!

  Hello Ross

  Here we have already for years running the packetnode using ax25
  drivers in linux.  http://sharon.esrac.ele.tue.nl (sorry in dutch)
  Different speed up to 76800 however we use SCC IDE controlers I think
  via the serial port ttyS0 ax0 will do also.

  Before we switched from DOS-6.11 to linux we used NOS or NET

  No GUI all very basic but reliable from 1987 till now

  I am looking for a packet program, which I can use to operate my
  Symek TNC3S at 57600
  but which has the kiss mode. Any one any ideas.
 
  Packet was in favour a few years ago and all the programs I can
  find
  are very old,  dont like the kiss mode,
  or cant talk to the TNC3S at 57600.

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.
