i cant interface NXP2148 with the GSM module. i have used the UART1 (through RS232 DB9 using RXD, TXD and ground) to interface with the GSM module at 9600. when i send the command AT<CR> through hyperterminal it accepts, sends back an OK when i SEND the same command through NXP2148 there is no response. my program is correct i have checked it at the hyperterminal. And i tried changing the cable also... but still no response. PLEASE HEPL!!!!
