Hi Gang,

I'm using an opto isolator on my RS232 comm lines to a PIC system.
I have discovered that many portable computing devices DO NOT MEET the
RS232 spec in that their maximum output is 5V, rather than the 12V
of the spec. Since I have to design for 'worst case' has anyone
encountered devices that put out less that 5V and 10mA when
signalling, or more than 12V and 30mA of the spec limit?

TIA

Robert
