Sounds like you're having flow control problems... I just overcame
the same thing when I upgraded the OS on my RT.. (CorrSrvc 1773).
I just couldn't get hardware flow control working to save my life
but this weekend I sat down for a couple of hours and got it working
with my "DCA Fastlink" (Trailblazer Clone).

In "devices", I have:
	pro dc
	ixp false
	dvam 0
	sns false
	aa false

and in the telebit, I have:

E0 F1 M0 Q1 T V1 X3     Version AA3.00-AB3.00
S00=001 S01=000 S02=043 S03=013 S04=010 S05=008 S06=002 S07=060 S08=002 S09=006
S10=007 S11=070 S12=050 
S45=000 S47=004 S48=001 S49=000
S50=000 S51=005 S52=002 S53=001 S54=003 S55=003 S56=017 S57=019 S58=002 S59=000
S60=000 S61=099 S62=003 S63=001 S64=000 S65=000 S66=001 S67=000 S68=002 
S90=000 S91=000 S92=000 S95=000 
S100=000 S101=000 S102=000 S104=000 
S110=255 S111=255 S112=001 
S121=000 

Other Pertinent information: 6150-25, IBM 4 port async, and standard
IBM Modem cable.

There's still a problem with Carrier Detect and getty... It seemed to
a choice between having hardware flow control or having getty work
right...  But if you're using it to dial out only, then you shouldn't
have to worry about that...  

Good Luck.
