I was just wondering what version of RS232 Standard are they complying to? Because, as far as my memory goes there is no such RS232 device (or RS232 standard) that gives or specifies 0Vdc in idle condition and 5Vdc pules (measured on CRO), during data transfer.


Kiran,
It seems to me they have invented their own standard ! They are playing with marginal operation; see what happens if you use 10 metres of cable !
