[comp.dcom.modems] Can V.32 modems connect to trailblazers ?

lars@iclswe.icl.se (Lars Tunkrans) (04/15/91)

I have tried to call a Trailblazer modem from my Norwegian made Semafor 9696a
V.32 modem. They didnt connect to each other.  

Is it reasonable to expect this to work ?  I dont know if Trailblazers have
any V.32 capabilites, and the guy I talked to knew even less.

If so, How would you set up the Trailblazer ?
 
Please email, I dont read this group very often.

Thanks, Lars.

	  I think you have to enable the V.32 option on the TB otherwise
	  it will only connect PEP... There may be another caveat, the time
	  the V.32 modem will wait for the v.32 handshake (3 sec max) and
	  the V.32 modem T1 timer  may be set for .03, .08 or 1.6sec and missing
	  the TB V.32 handshake. If I recall, the TB does PEP first and then 
          then V.32.

The T-2500 and T-1600 will talk V.32.  The trailblazer is currently
documented as not doing V.32.

One of the engineers that I work with had great difficulty getting a T-2500
to talk with a standard V.32 modem.  It turned out that there was a register
setting for enhanced V.32, and our T-2500 somehow got in that setting.

There is a register (don't recall which one off the top of my head) that
controls whether the PEP tones come first or last. I have my chat script
set up for `PEP last' when calling a V32 site. Other than that the factory 
defaults seem fine. Your mileage may vary, of course ;-)

You don't. The Trailblazer Plus doesn't support V.32. The T1600 supports
V.32 and the T2500 supports both V.32 and PEP. Both support V.42/V.42bis.
