So, in my project i need to test a rather complicated modem, and i'm trying to send commands using a USB-RS232 adapter linked to a TTL logic converter.
I need a program like putty that lets me send specific number in hexadecimal (because the alphabet of the target integrated circuit is different- GSM alphabet) and that lest me set the endianess and also receive the information and display in exadecimal... any pointers?
Best regards,
