README - TNC host setup - 1 Mar 91 - (c) 1990 Howard Goldstein N2WX
Notes on TNC, drivers and test code:
0) TNC Commands related to host mode:
BLP ON|OFF. You must turn BLP on and enter transparent mode
to run the host code. Once BLP is on, subsequent RESTARTS and power up
cycles will be directly and silently into transparent mode and
it will continue to do so until you turn BLP back OFF or the bbRAM fails.
CONMODE TRANS|CONV. You MUST set CONMODE to TRANS else
the first time youre connected you'll lose the DLC connection!
PARITY 0/AWLEN 8. These MUST be set for no parity/8 bits!
MON ON|OFF. If you have BLP ON and MON ON, >ALL< packets -
data, command, beacons, whatever - will be sent to the host on BLP
channel 0x71. If you're being inundated with countless frames when
debugging you might want to turn monitor off to avoid the mess.
MYDLCNUM. Set to a non-0 number < 255 (TNCs should start
at 1; hosts should start at 254 and go down). When non-0,
the addressing procedures for multiplexing TNCs on the RS232
port are enabled.
DEFLTDLC. Effective only when non-0 MYDLCNUM, this parm
tells the TNC what the DLC address is of the host (ex, MTHOST).
Default is 254.
