instrument-control

[kees]

I have trouble writing to the serial port with the "srl_write(port, 
data)" function.
The data that the the write function accepts or transmit is in ascii 
format however the instrument that I would like to communicate with 
accept only byte values from 0-to-255.

For instance to put the analyzer in remote control I have to send a byte 
with the value of 69. If I send the character "E" it will go in the 
remote mode. However if I send the value 69 the two byte values 54 and 
57. Or when I communicate in "cute-com" I can send the hexadecimal value 
of 0x45 and that works too.

So my question is how do I use the srl_write function to send byte 
values to the analyzer?
