you can use Ultraedit to solve your problem , or if you have a Norton Commander (NC) you could use the edit feature and that should solve your problem about the text wraping .
you could try to use Word for opening your file ,maybe it would help solving the wraping problem , but the UltraEdit absolutely will solve the problem ,cause i've had such problem , it is something called Dos Text format.
The RealTerm which has been mentioned has a capture feature , did you used it also , did it worked ?
