Hi.. I want to interface a GPS & a GSM module with my 8051. But since it only has one UART, this is a problem.. Can anyone pls explain how to this? & is it actually practically feasible?

Do you HAVE to use a 51.... Can you get hold of the 52 version? The 52 has two RS232 ports

Hi Twisted_transistor,
What do you want to do with GSM module ? what is your application?
Do you want only to send sms or want to read sms as well ?
If you want to send sms then you can use 8051,
Connect TX pin of 8051 to the RX pin of GSM modem
and connect RX pin of 8051 to the TX pin of GPS modem
but by this method you won't be able to read sms
