Full Implementation of Fax Class1 Protocol for AT Modem(GSM) in ANSI-C (send fax only) 1. Possibility to send ASCII Text to any FAX. 2. Many pages in same connection. Program running in interrupt routine and must be optimized for atmel Atmega324p (limited Flash/SRAM), accurately we need a collection of routines to send a ASCII text to any fax machine including rendering ASCII text as a raster image (37 characters: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E. F, G, H, I, J. K, L, M, N, O. P, Q, R, S, T. U, V, W, X, Y, Z, SPACE). each character must be generated before and saved as raster image in the program code, we are using only 1 font like ARIAL Font-size:8 capital letters, it can be fix storage in the program code. because of the limited resources text can not storage in a array, there is a already a routine what give each routine call one text line in ASCII(pointer) back. it is god but not necessary to programmed before with WinAVR, if the Program is written in MiniGW and following the follow structure, we are able to port it with your help, remember the limited resources int main (void) { } ISR(USART0_RX_vect) //interrupt { //USART Receive 1Byte } void USART0_write(uint8_t data) { //USART Send 1Byte }
