-
- Hello and thanks for reading this posting.
-
- We are having trouble with FBB(5.15) + BPQ(HF&VHF) + modem. Modem does not
- work properly in answer mode (it does not answer incoming calls) but it works
- in originated mode. Modem is internal 2400 and works very good with other
- terminal programs (Telemate 3.10). The computer is IBM PC-AT (10 MHz).
-
- If you can help us, please send an email to me. I'd love to hear from
- you!
-
- MANY thanks, in advance.

- To: ham-digital@ucsd.edu
-
- Maybe I'm missing something obvious, but why not just kermit into
- a unix host and use the DEC box as a dumb term? For SLIP to be useful,
- you would really want a multitasking OS, wouldn't you? Unless you
- made a SLIP TSR thing just to run a telnet or ftp daemon (although you'd
- still need a multitasking OS if more than one person wanted to log in)...
- sounds like an interesting hack though, if just for the sake of a hack,
- but I thought hacks were supposed to be insant *looking* solutions to *real*
- problems...

- It is like the KPC-4 only built in a slightly larger case than the KPC-3.
- It has two modems 1200 baud and 9600 baud. You can operate both at the

- cross-banding. I have had mine for about a month operating 1200 baud on
- two meters and 9600 baud on 440. I am using it with KAGOLD software.

- several NUMNODES.

- Just thought I would throw my two cents worth your way I owned a

- with it then then the KPC-3 is the way to go . If you plan on dabbling
- in HF packet ax.25 protocol then get the MFJ . For the same price you
- get one mode on HF . Hope this muddies the waters a little :-)
